LaMarcus Aldridge is scheduled to undergo an MRI on his bruised left knee.

Aldridge suffered the injury in a collision with Otto Porter Jr.

Aldridge limped to the locker room and didn't return.

With Kawhi Leonard out, Aldridge has taken a larger scoring load. Aldridge entered Tuesday's game having scored 178 points in his last five outings, which is the most over a five-game span in his career.

“Considering the way he’s been playing and our recent success in those games, we are at the point where if LaMarcus gets a cough, a cold, we are in deep trouble,” Manu Ginobili said. “Hopefully, it’s not serious because it’s going to be really tough to score without him and we have tough games against teams that need to win. We really need him.”
