Los Angeles Clippers forward Blake Griffin has been diagnosed with a medial meniscus tear in his left knee and, according to a Los Angeles Times report, will likely have arthroscopic surgery early next week.

The Times, citing NBA executives, reports Griffin is expected to miss eight weeks but should be recovered by the start of Clippers training camp in October.

Griffin, as a result, will miss the upcoming Olympic Games in London.

"We're relieved that this does not affect Blake's ability to be ready in time for training camp," Clippers coach Vinny Del Negro said in a statement. "Missing out on the Olympic experience will be tough for him to take. I know how dedicated he was to doing that. We're glad we can get this fixed now and take advantage of the available time for him to fully recover."

New Orleans Hornets rookie Anthony Davis, the NBA's No. 1 overall pick out of Kentucky, was named to replace Griffin on Team USA's 12-man roster Friday.

Davis dressed for a 113-59 exhibition victory over the Dominican Republic on Thursday night in Las Vegas.

USA Basketball said in a statement that Griffin reported he was experiencing discomfort in the knee during a scrimmage at Team USA training camp. Griffin missed Thursday's game.

"Blake worked extremely hard in our training camp and certainly would have been a valuable contributor," USA Basketball chairman Jerry Colangelo said in a statement. "This is another unfortunate injury, but we have to continue to move on and we're very fortunate to have Anthony Davis available. Anthony offers our team additional height and length, and this will be an incredible experience for him."

The Clippers said in a statement that Griffin would undergo an MRI exam once he returned to Los Angeles and then will be evaluated by Dr. Neal ElAttrache of the Kerlan-Jobe Orthopaedic Clinic on Sunday.

Colangelo suggested the soreness in Griffin's knee was related to an injury he suffered during the 2012 NBA playoffs.

"The reality is, that injury took place at the end of the season," Colangelo said. "And he had an option to get scoped and he opted not to get scoped. And so, I guess he aggravated it."

Griffin did not show any obvious signs of an injury on Wednesday, and a source told ESPN.com's Marc Stein that Griffin's knee "swelled up" after the scrimmage.
