Tiki Barber has filed papers to come out of retirement. The 36-year-old running back will attempt to step onto an NFL field and play again after "retiring" for four years.
It is unknown what the interest level is for Barber right now, but undoubtedly some teams would be interested in seeing if the former New York Giant still has something left in him.
Of course he won't be the first athlete to pull the old switcheroo when it comes to retirement. Countless other athletes have called it quits only to change their minds. So who were they? And how did they do? Look ahead at 10 prominent athletes who came out of retirement.
Mark Martin became famous while driving for Rousch Racing. He spent the majority of his career with the team and finally announced his retirement after the 2005 season. He spent that year saluting and thanking the fans for all that they had done for him during his racing career.
Unfortunately, contract issues and other dilemmas left Rousch racing without a driver for the No. 6 car in 2006. Martin agreed to come back and forgo his retirement.
After the season it was announced that Martin would run a "toned down" schedule for Ginn Racing, splitting time with another driver. He was successful right away and nearly competed for a spot in the season-ending Chase despite missing a handful of races. Martin continued to run a limited schedule in 2007 and 2008.
Finally, in the summer of 2008, Rick Hendrix and Mark Martin came to an agreement that would see Martin race again full time in 2009. He has competed for the team since then.

After moderate success with New Orleans, Williams was traded to the Dolphins in 2002 for multiple draft picks. Williams thrived in Miami. In his first year with the team he led the league in rushing and was voted to his first Pro Bowl.
Then in 2004 it was announced that Williams had tested positive for marijuana and would face a four-game suspension from the league. Williams retired instead.

He would return to play in the 1992 All-Star game. Johnson was awarded the game's MVP award and was planning a full-time return, but due to player protests, he retired yet again.

If it wasn't for Brett Favre, Roger Clemens may just be the king of fake retirements.
After years with the Red Sox, Blue Jays and Yankees, Clemens announced his retirement in 2003. During his "final" season with the Yankees, Clemens recorded both his 300th win and his 4,000th strikeout.
Once the season ended, Clemens decided to forget retirement and instead signed on with the Houston Astros. He won the Cy Young Award during that year with the Astros.
His future was uncertain yet again during the offseason, and again Clemens decided to come back and pitch for the Astros. Clemens finished 2005 with a ridiculous 1.47 ERA and was again a top pitcher in the league. He retired again after the season.
But then during the 2006 season, it was announced that he would come back, yet again, with the Houston Astros. He returned in June and finished out the season.
He retired yet again after the 2006 season but wound up pitching for the New York Yankees during 2007 anyway. It was his final season in MLB.
Three teams. Four retirements. Way too many news reports.
That basically sums up Brett Favre's final years. Favre conducted a circus every single offseason with the Packers, Jets and Vikings, leading countless experts to guess whether or not he was coming back for another season.
Hopefully he has officially retired after this past season.

He won seven straight Tour de France titles upon his return.
He would retire again in 2005 but return for the 2009 season. Armstong still cycles today.
The greatest basketball player of all time retires three times and comes back twice. His first retirement was for baseball and his second because he thought he was done playing the game.
