The Knicks’ interest in Cavaliers point guard Baron Davis could be tempered by a revelation that his recent back injury could be more serious than previously thought.

CBSSports.com reports Davis, who hurt his back at the beginning of training camp, is seeking a second opinion on the injury. The Cavaliers belief after Davis’ physical is the back issue could keep him out weeks.

Davis wants to play in New York if he becomes an amnesty free agent but the Cavs are waiting before making the decision. The amnesty process is complicated and teams under the salary cap put in bids for Davis’ services, meaning he can’t initially pick his own destination.

The Knicks are over the salary cap and must wait to see if Davis is claimed.
