Auburn forward Chuma Okeke went down with 8:08 remaining in the second half of the Tigers' Sweet 16 clash with No. 1 seed North Carolina with an apparent leg injury.
Okeke crashed to the floor after colliding with UNC's Cameron Johnson under the rim. He was seen grabbing his left knee before being helped off the court and into the locker room. Auburn announced that Okeke would not return to the game and was being taken for x-rays.
Several members of Roy Williams's team checked in on Okeke as he exited the game.
The 6'8" sophomore led Auburn with 20 points, 11 boards, two steals and a block before leaving the game.
