New Orleans Hornets rookie forward Anthony Davis had to be helped off the court after suffering a sprained left knee with 5:45 remaining in the fourth quarter during Wednesday night's game against the Sacramento Kings. When Davis left the court he could barely put pressure on his left leg as he walked. The injury came when Davis stood his position in the post to draw an offensive foul, but former Hornets guard Marcus Thornton fell hard on Davis' left knee after colliding into him underneath the basket. After the collision,Davis quickly grabbed his left knee and grimaced in pain before Hornets trainer Jon Ishop, coaches and players came out on the court to see about him. Davis did not return after scoring 13 points and grabbing 10 rebounds in the Hornets' 121-110 loss to the Kings. `I think he's OK, but I don't want to jump the gun,'' Hornets Coach Monty Williams said. ``I didn't see the play yet, but he said Marcus landed on his knee. He said he's a little sore.'' Davis, the No. 1 overall pick in the 2012 NBA draft, is expected to undergo an MRI test on Thursday to determine if he has any structural damage. He was not made available to the media after the game. On his way to the team bus, however, Davis was limping noticeably. ``I'm just glad it wasn't a buckle or a ligament or anything like that,'' Williams said.
