With the 2012 Summer Olympics in London set to begin in just 12 days, Team USA has undergone a vital alteration on its basketball squad, as No. 1 NBA Draft pick Anthony Davis will replace the injured Blake Griffin.
Meanwhile, the American 4x400-meter relay team will lose the services of Debbie Dunn.
Additionally the US tennis roster was officially announced, along with the final Olympic roster which revealed that, for the first time, there will be more women than men representing the USA at the Olympics.
Basketball: Griffin in, Davis out
Broderick Turner of the Los Angeles Times reported on July 12 that Griffin of the Los Angeles Clippers suffered a torn medial meniscus in his left knee.
Fortunately for Griffin and the Clippers, the injury shouldn't cause him to miss any of the NBA regular season.
His injury occurred on Wednesday, the night before Team USA's exhibition against the Dominican Republic and Davis replaced him on Thursday night in Las Vegas.
The rookie New Orleans Hornet from the University of Kentucky went for nine points in the 113-59 victory and was officially added to the roster on July 13 (via USABasketball.com release).
He will by-far be the youngest player on the Olympic basketball roster, beating out James Harden by nearly four years.
How will Davis replacing Griffin impact Team USA's performance?
He'll join Tyson Chandler and Kevin Love, and together, they should be able to dominate the opposing centers in London.
Team USA will miss the versatility and big-play ability of Griffin, but Davis' Mr. Fantastic-like physique will add an additional defensive dimension to the squad.
Griffin is more of an offensive threat, but with elite scoring-threats like Kobe Bryant, LeBron James and Kevin Durant on the roster, the Americans should be able to barrage their opponents with buckets.
Track and Field: Debbie Dunn will not run 4x400-meter relay
Sprinter Debbie Dunn tested positive for elevated testosterone levels, and subsequently removed her name from the US Olympic roster (via ESPN.com).
She was not set to represent Team USA in the 400-meter dash, as she finished fourth (one place out of the running) at the US Olympic Trials in June.
But, her fourth place finish likely would have garnered her a spot on the 4x400-meter relay roster.
Though the loss of a talented runner could be detrimental, the American sprinting squad should still be fit to defend its gold medal in the 1,600-meter relay from 2008.
Dunn's replacement hasn't been officially announced but the short list includes the fifth-place finisher at the Trials Diamond Dixon out of Kansas who finished just 0.10 seconds behind Dunn.
Another possibility would be US 200-meter dash champion and 2008 4x400-meter relay member Allyson Felix.
Either way, the Team USA women's sprinters are at no shortage of speed.
Tennis: Some of the game's biggest stars to highlight US tennis roster
The men's and women's tennis rosters were announced recently (via Washington Times).
On the women's side, Venus and Serena Williams headline the talented women's roster, as they will be seeking their third gold medal in doubles, along with the second-place doubles team at Wimbledon, Liezel Huber and Lisa Raymond.
Joining the Williams sisters in the singles competition will be Varvara Lepchenko, and Christina McHale. Venus will be competing for her second gold in the singles competition.
Serena and Venus are the two best chances for a tennis gold medal. Serena's play has been improved lately, as evident by her recent Wimbledon victory, but Venus has the better rap sheet at the Olympics.
The men will be led by 2004 gold medalist Andy Roddick. Roddick will also compete in doubles alongside John Isner—arguably Team USA's second-best hope for a medal against what should be some stiff international competition.
The other doubles team will be Bob and Mike Bryan, bronze medalists at the 2008 Olympics.
Joining Roddick and Isner in singles will be Ryan Harrison and Donald Young.
A Title IX Victory: Women to outnumber men on Team USA at 2012 Games
The US Olympic Committee last week that the 530-member Team USA roster will be compromised of 269 women and 261 men, marking the first time females outnumbered males for Team USA at the Olympics (via Kelly Whiteside | USA Today).
Team USA officials were very proud of this monumental achievement.
"It speaks to Title IX," Teresa Edwards, the U.S. Olympic team chef de mission and five-time medalist in basketball, told USA TODAY Sports. "It's evident where we've come from especially with women in sports. I'm very proud of that — not so proud that I want to make the men jealous because a lot of men play a role in where we are now — but I'm proud to know that we've come this far."
