All-Star forward Blake Griffin left the Team USA training camp Wednesday because of a knee injury and the injury reportedly will sideline him for about eight weeks.

The Los Angeles Times reported Thursday the injury is a torn meniscus that will require arthroscopic surgery and keep him out of action for about two months. He will miss the Olympic Games.

Griffin was injured in a team drill on Wednesday and he returned to Los Angeles for an MRI.

Anthony Davis, the No. 1 pick in the 2012 draft and one of the final players cut from the roster last week, replaced Griffin on the U.S. roster. Davis suited up for the U.S. team in Thursday's exhibition game victory over the Dominican Republic at the Thomas & Mack Center in Las Vegas.

Davis, who was already in Las Vegas when he was summoned to replace Griffin, turned pro after his freshman year at Kentucky and is the only member of the U.S, team who does not have NBA experience.

Griffin injured the same knee in the playoffs and was limited for the final three games of the first-round series against the Memphis Grizzlies.

Griffin suffered multiple knee injuries at Oklahoma before entering the draft in 2009.

He signed a five-year, $95 million deal with the Clippers on Wednesday.
