Troy Ave, whose real name is Roland Collins, 33, was undergoing surgery to have bone fragments removed from his leg.

He is facing attempted murder and weapons possession charges after he was caught on video opening fire backstage during a T.I. concert at Irving Plaza Wednesday night.

Troy Ave’s court date on Centre St. was postponed Saturday as the rapper-turned-gunman remained in the hospital, nursing a self-inflicted gunshot wound suffered during a shooting at Irving Plaza.images
