Brooklyn Nets guard Kyrie Irving appears to have been cleared of a concussion after being forced out of Tuesday's 115-107 win over the Chicago Bulls.

Irving went down on the back court after being collected accidentally by a stray elbow from Bulls center Nikola Vucevic.

The 29-year-old, who had played 21 minutes with 13 points, three rebounds and five assists to that point, did not return to the game.

Irving's issue would be an additional concern for Brooklyn with James Harden already sidelined with a hamstring injury, although he is close to a return.

The Nets guard suffered a facial contusion and underwent concussion tests but Nets coach Steve Nash revealed it looked like he was in the clear.

"No signs of a concussion," Nash said post-game. "He had an x-ray which was inconclusive so we’ll really just have to look again in the morning.

"Probably be rescanned and all that when we get home and we’ll take it from there."

Kevin Durant played a key role for the Nets with 21 points as they improved their record to 45-24, firming up second spot in the East, ahead of the playoffs.

Durant added about Irving: "I thought he would be alright. I know those - he mixes it up a lot with the big fellas - so he might catch an elbow here and there.

"Kyrie, he plays with such toughness and competitiveness, I knew he'd get up, but I knew he took a nice one, a nice elbow to the face.

"Hopefully he gets checked out tomorrow, sees everything is alright and we move forward."

The Nets are due to play the San Antonio Spurs on Wednesday.
