Blake Griffin off Olympic team with knee injury - CBS Atlanta 46

Blake Griffin has officially withdrawn from the Olympics and Anthony Davis has been added to the U.S. basketball team's roster.

Griffin needs surgery to repair torn cartilage in his left knee and joins a lengthy list of American stars  sidelined this summer.

Davis replaced him in the Americans' 113-59 exhibition victory over the Dominican Republic on Thursday in Las Vegas, scoring nine points in the fourth quarter. The No.1 overall draft pick couldn't be put on the 12-man roster for London until Griffin had withdrawn Friday.
