Rookie big man Anthony Davis will take Blake Griffin's roster spot on Team USA after Griffin tore his left meniscus, according to Adrian Wojnarowski of Yahoo! Sports:

"

As expected, Anthony Davis has been chosen to replace Blake Griffin on the Team USA roster, a source close to Davis tells Y! Sports.

According to the Los Angeles Times, Blake Griffin has reportedly suffered a torn meniscus in his left knee:

"

Blake Griffin has been diagnosed with a meniscus tear in his left  knee and will have arthroscopic surgery probably early next week, according to NBA executives who were not authorized to speak publicly on the matter.

"

The Clippers star power forward will miss the Olympics, but the recovery period is reportedly eight weeks. That means he should be fine to play when the season starts.

According to Yahoo! Sports' Marc Spears, Griffin doesn't look like he'll be making a triumphant return to the national team in London:

Griffin was injured during a scrimmage on Wednesday and returned to Los Angeles, where he was expected to have an MRI.

This is very bad news for Team USA, as the frontcourt has worn extremely thin after injuries to Dwight Howard, Chris Bosh and now Griffin.

The 23-year-old superstar was expected to see some pretty substantial playing time, but will now likely give way to Anthony Davis for the 2012 London Summer Olympics, per Jeff Zillgitt of USA Today.

According to CBS Sports' Ben Golliver, Griffin "experienced discomfort" in his left knee after "completing a full practice."

Griffin's injury must be particularly frightening to the Los Angeles Clippers after the team literally just inked the former Slam Dunk Contest champ to a monster five-year extension that could be worth up to $95 million.

Prior to his rookie season, Griffin had season-ending surgery on the same knee that he injured on Wednesday. The injury forced him to miss the entire 2009-10 season. Griffin also found himself on the bench during stretches of the 2012 NBA playoffs nursing a hyper-extending left knee.

Griffin hasn't missed a regular-season game over the last two seasons, posting career averages of 21.7 points and 11.5 rebounds per game.
