Brandon Knight's MRI on his hyperextended right knee came back negative, but the second-year point guard will be out awhile.

Pistons doctor Ben Paolucci visited Knight before Friday night's game with Indiana, but coach Lawrence Frank said he's day-to-day and won't play again until he's 100%.

Knight suffered an injured knee and ankle in the victory against Charlotte on Wednesday and missed Friday night's game. The MRI showed swelling but no damage.

"He has fluid behind his knee," Frank said. "You can see it. He can't really jump, and he just doesn't have total confidence in it. The MRI, like I said, was more for precautionary reasons. It didn't show anything other than what we already diagnosed. It'll be day-to-day. He'll be taking some medication and just kind of see how he does in terms of trying to get the swelling down."
