OG Anunoby’s Knicks return ‘real close’ with 76ers rematch on tap

Tuesday could be the night the Knicks’ frontline starts to get whole again.

OG Anunoby has been upgraded from out to questionable for the rematch of Sunday’s ugly loss against the 76ers — and he could make his first appearance since Jan. 27 due to an elbow injury that required cleanup surgery.

The valuable two-way wing has been scrimmaging with the Knicks for several days, and Tom Thibodeau described Anunoby as “real close” to returning to the lineup.

“I think it’s a normal protocol. He’s had to meet markers along the way. And the final one is going back to the doctor to make sure he signs off on it, as well,” Thibodeau said after practice Monday in Tarrytown.

“Our medical people, the doctors, him. It’s a combination of everybody. He’s real close. We have to let it play itself out.

“But I feel good watching the way he’s progressed, just everything that he has been cleared to do. He’s taken contact. He’s gone through practice. His conditioning is good. We are hopeful.”
