Star guard John Wall left the Washington Wizards' loss on Sunday night late in the fourth quarter with a knee injury.
Wall exited the 116-104 loss to the visiting Dallas Mavericks with 1:14 to play after running into Dallas' Jeremy Evans.
Wall said he wasn't sure of the extent of the injury.
"I have no idea right now," Wall said. "I just did an X-ray and did not look at it. I just left."
Wall led the Wizards (8-10) with 28 points. He is averaging 18.4 points and 8.
