NEW YORK (AP) An NFL spokesman says that the doctor who reversed course on Redskins quarterback Robert Griffin III's post-concussion playing status has resigned and been replaced as the team's independent neurological consultant.

The NFL's Brian McCarthy tells The Associated Press on Saturday that Robert Kurtzke left the consultant program operated jointly by the league and the players' union.

McCarthy says Kurtzke will still monitor Griffin's status and determine when he can be cleared to play.

He says Abraham Kader is the new NFL-NFLPA independent neurological consultant assigned to the Redskins.

A message left by the AP at Kurtzke's office Saturday was not immediately returned.

The Washington Post first reported on Kurtzke's resignation and continued involvement with Griffin's case.
