Roger Clemens on his first of many stops after coming out of retirement, The New York Yankees.
Just when you think Father Time is catching up with some of these athletes, they decide to call it quits. But then there are second thoughts. They come back for another year. Then it may happen again and again. Some athletes just don't know when it is their time to go.
Bleacher Report observes some of those undecided athletes and their comeback moments.
Giving basketball one more shot with the Wizards. I mean there was no Chicago White Sox reunion planned.
Michael Jordan was the face of the NBA during his prime and his championship winning era with the Chicago Bulls. Then his time of stardom was over and the once NBA legend became just another retired future Hall of Famer.
Retirement did not last Jordan very long, as he decided to take a role in the Washington Wizards' front office. Then the Wizards' front office made its way back onto the court and there was No. 23 playing again.
He played his final game after the 2002-2003 season. But his presence in the game of basketball still can be felt. Recently, he became the owner of the Charlotte Bobcats.
He still stays in the spotlight with his famous Hanes commercials as he rocks a Hitler-like mustache.
Calling it quits? Not quite yet. Give Pac-man a shot before you do it, Floyd!
Floyd Mayweather retired the first time after his bout with Oscar De La Hoya. He won that match, but many critics say that he should not have. Talks were heating up in the media about a potential re-match for Mayweather to prove himself 100 percent better than the Golden Boy. But he refused and decided to go into retirement.
It seemed like a chicken move. He ended up coming out of retirement after De La Hoya announced his very own retirement. Mayweather mentioned that if there was enough money on the table, he would come back.
In fact, he did. He has continued to win as a boxer. Recently, he has been avoiding the big fight against Pacquiao. Fans and critics want it, but he refuses. Would anyone be surprised if he retires before this bout happens and then comes out of retirement?
George Foreman is now the promoter for his "Lean, Mean, Fat Reducing Grilling Machine", but back in the 70s, Foreman resembles Floyd Mayweather a bit with his approach on retirement.
He lost a very hard-fought battle with Muhammad Ali in the "Rumble in the Jungle." He retired a year later. Then he decided he had unfinished business in the ring, but it would take 10 years for him to make the final decision on coming back.
Foreman returned at the age of 45 in 1994. This was before "Rocky Balboa", so he was in a league of his own. Yet, he rose above the challenge and was able to win a Heavyweight Championship. This hot streak would last only four years, but he made the best out of it.
Once your hair starts to turn gray, you know it may be time to think of retirement. Borg was one of the best tennis players of his day with his No. 1 overall ATP ranking. But his comeback tour was not one of the best. It could go down as one of the worst.
He retired twice because it was that dreadful. It included a 10-year decision to retire again, which definitely took a toll on his game. But the former all-star remains active...as a senior.
His matches include players like John McEnroe and other old tennis buddies. Soon we may hear about his decision to retire from the seniors tour and then come back again.
Typical Bjorn Borg.
Run, Ricky, Run!
Ricky Williams decided to call it quits after several run-ins with the substance abuse policy and drugs in the NFL.
His first cleat hanging occurred in 2004 after he tested positive for marijuana. He was playing for the New Orleans Saints, but deep inside, his behavior caused him to be a devil. He was disobeying multiple orders by the NFL on drugs.
He returned in 2005 after having second thoughts. That would not last long as he would be suspended for an entire year afterward. 2006 caused a drought in the great legs of Ricky Williams. Many started to believe that this once greatly talented star was starting to go off his rocker.
Williams played for the Toronto Argonauts in 2007. The Dolphins made him promise that he would be back.
The Miami Dolphins were able to forgive and forget. They allowed Ricky Williams to step on NFL grass one more time. He was injured pretty quickly, but that would not slow him down afterward.
Just recently, Ricky Williams ran for 1,000 yards in a single season. The last time he did this was six years ago and that is a record. He still has it in him.
Only a countdown can begin for Ricky Williams' fourth intermission from the game.
The Iceman has gone cold and could be heading into retirement.
Chuck Lidell has had an interesting past few months. He was featured in "The Ultimate Fighter" and he was scheduled for a bout against Tito Ortiz.
The Ortiz fight never happened, but he was slated to face Rich Franklin in UFC 115. The hype was all over the media for what was suspected to be a make-or-break moment in the career of Chuck Lidell.
He was out to prove that the Iceman was still hot. But he failed miserably.
Rich Franklin knocked him out in the first round. This was the third straight knockout for Chuck Lidell, which could have knocked him out of the octagon forever.
The latest in Chuck Lidell's retirement saga is that UFC President Dana Whit has said, "The Iceman" will not fight in the UFC ever again."
Who knows if he will ever step into the Octagon to fight ever again. Could a fourth straight KO for Lidell be in order?
Pele back in the spotlight as he tries to make the New York Cosmos big again.
Pele was named one of the greatest athletes ever by several media outlets and sports committees. He was the face of soccer in his era. Brazil had the best player ever on their team and they made the best of it.
Pele was able to hurdle over anything in his 20-year career. He even included a stint with the New York Cosmos. But the fairy tale ended in 1977.
The legend's presence in the sport has not gone unheard. He continues to pull for the Cosmos and has been named one of the team's owners. His goal as of early August 2010 is to try and field together a Major League Soccer team.
We have definitely not seen the end of Pele in soccer. There has not been any word as of yet on whether or not he will play for the Cosmos if a huge return is in the final stages with the MLS.
Lance Armstrong in his "final" Tour De France
One Man. One Dream, One Testicle. One More Shot.
That seems to be the way that Lance Armstrong's recent comebacks have been embodied as a slogan. Lance Armstrong is the All-Around Best American to show determination in a sport.
He took cancer down his first time. Retirement was cancer's only way of telling Lance Armstrong to slow down, but he refused. In 1998, Lance Armstrong got right back on that bike with hopes of winning a Tour De France.
He would not only accomplish his dream, but he would win it seven consecutive times!
In 2005, he would announce his first retirement from cycling. He would end it with his seventh consecutive win.
He would compete with Astana and decide to come back one more time for No. 8. He fell short, but the effort was what counted.
In 2010, he announced that the 2010 Tour De France would definitely be his last. Armstrong crashed a few times that put him out of contention of winning, but he pedaled on. He finished 23rd and Team Radioshack was able to win in Team competition.
Have we seen the last of Lance Armstrong?
Roger Clemens walks off the field in a Yankees uniform in 2007.
Roger Clemens was last seen donning a Yankees uniform in 2007. But he has been around the block, as he has worn the Red Sox uniform, the Houston Astros and Toronto Blue Jays jerseys, and several minor league jerseys along the way.
He changed his mind on retirement from Major League Baseball three times. I guess he was taking notes from some of the other men on this list.
The Rocket made a ton of money his last year as he was making big dough for every pitch. The punchline comes in when you realize that he was only pitching for half a season.
Clemens is still active and seems to enjoy throwing batting practice for his son and the Astros from time to time. Clemens could still be looking for a contract as he has never formally announced his retirement from baseball.
His name showed up in the Mitchell Report and has been under some heated debate on his steroid stance. This could be the main reason teams have backed off him...or maybe his age is the main reason.
Note to Roger: Announce your final retirement.
The man, the myth, the legend of retirements.
What a surprise! Brett Favre is the dictionary definition of "retirement" and "undecided."
He cried while announcing his first retirement with the Green Bay Packers and then signed with the New York Jets. An addiction to retirement soon followed as Brett Favre came out of retirement one more time to sign with the Minnesota Vikings.
Currently, Favre is keeping us on the edge of our seats as he has yet to make his next decision on his future. I mean, c'mon! Hurry up Brett! Soon enough, we will all be older than Brett Favre before he makes his call.
LeBron James was able to make his idiotic free-agency decision on an ESPN hour-long special without consulting his former team. Brett Favre should show this fool how it is done with class.
Brett Favre will forever be The King...of retirements at least.
