Celtics guard Kyrie Irving downplayed his shoulder injury after Boston topped the Knicks, 128-100 Thursday night.

Irving left Thursday's game with 3:34 remaining in the fourth quarter after tweaking his right shoulder on what he called a "weird play." He sat on the bench with ice on his shoulder and didn't return as the Celtics already had secured the victory. 

"It's like I got caught up as I was trying to get the ball out and pass it to Marcus (Morris) for a 3," Irving said, via NBC Sports. "It just caught me weird on my shoulder. So it's probably an AC joint or something like that. I'm not diagnosing myself, I'm pretty sure. I saw the doctors afterward and they said AC joint or something going on there, but I'll be alright."

Irving had a strong night as he scored a team-high 22 points on 9-of-15 shooting and went 3-for-6 from 3-point range. He added eight assists and four rebounds over 30 minutes.

The Celtics fell 117-109 to the Knicks on Nov. 21, and Irving said after the game he was pleased with how Boston played this time around. 

"I think I said it at the last media session we had at practice [on Wednesday], just a lot different identity,” Irving said. "For us, just having a lot more fun, making sure we are paying attention to detail and making sure that we’re playing at a level that we all demand out of each other.”

Boston has won four straight and the team holds a 14-10 record. The Celtics have a day off before facing the Bulls (5-20) on Saturday.
