Bucks rookie Jabari Parker suffered a left knee injury early in the third quarter of Milwaukee's 96-94 victory over the Phoenix Suns Monday night.
Parker's left knee buckled without contact as he made a drive in transition and he was unable to leave the floor under his own power. He was carried off the court by teammates Zaza Pachulia and Johnny O'Bryant.
"As of right now we don't know anything. They'll do all the tests tomorrow and we'll be able to report something then," Bucks coach Jason Kidd said after the game.
