TORONTO – RJ Barrett’s index finger wasn’t just cut open last week in Dallas, but temporarily dislocated.

Barrett said he received six stitches after his right index finger popped out and caused the laceration in the opening minutes of the Knicks’ overtime loss to the Mavericks on Dec. 27.

“So my own [left] hand went into my other hand and my finger bent backwards and popped out of place, which caused the laceration. So yeah, that’s what happened,” Barrett, a Toronto native, said before missing his fifth straight game Friday against the Raptors in his hometown. “You always wanna play, definitely at home. It’s kind of disappointing, but I’m still happy to be back.”

MSG TV announcer Mike Breen said on the air later during the Texas road trip that Barrett’s bone could be seen on video replays before he headed to the locker room, but the Knicks later corrected him and Breen clarified to say that a tendon was visible.

“It popped out. I popped it back into place. I didn’t see [a bone]. I was told after it was more like tendons, I guess,” Barrett confirmed. “But yeah, so I looked at my hand, it was definitely a laceration right there.

“So, I immediately just walked out and got it stitched up. I still have stitches in right now. … But oh, yeah. It was painful.”

The 22-year-old Barrett said he expects to have the stitches removed in the coming week after the Knicks return to New York. He said he’s been spot-shooting and running in recent days and hopes he won’t need much ramp-up time to return to action.

“Whenever I’m cleared and feeling good, I’ll be back,” said Barrett, who is averaging 19.7 points in 35 games this season. “The problem is, it’s a healing process, so I can’t force my body to heal. Whatever happens, like I said, I’m going back to the doctor this week, so we’ll figure it out.

“It’s weird [missing games]. … It feels weird. But yeah, just trying to do what I can, really, stay in shape the best I can, shoot, do whatever I can.”
