The Knicks announced Carmelo Anthony is questionable for Wednesday night’s game vs. the Pistons and called his injury “a stiff/sore right knee.’’ Anthony said Monday night the medical staff has been unable to determine the exact nature of the injury but said there wasn’t structural damage in regards to an ACL sprain or tear. Anthony said he felt stiffness in the back of his knee for two weeks. Knicks coach Mike Woodson responded defiantly Tuesday to a question from a radio host wondering if Anthony was hurting that badly to not return to the game Monday night in Cleveland after taking a spill in the second quarter. Anthony left the game with an injured right knee with 6:51 left that he said afterward has troubled him for two weeks. ESPN Radio host Robin Lundberg asked Woodson on the coach’s weekly spot if he bolted the court partly because the Knicks were down 22 points and he didn’t want to play at less than 100 percent on the second night of a back-to-back. Woodson reiterated Anthony had asked out of the game just before his clumsy spill after taking a pass at midcourt from Jason Kidd with no Cavalier around. “I definitely don’t agree with that,’’ Woodson said. “Melo has been a driving force of what we’ve been about. Anybody (who) thinks that way, I wish you wouldn’t think that way – (that he walked off because the game was out of hand. A 22-point lead in this league is nothing.’’
