McCown will visit with a specialist on Monday to examine his injured back, and the injury could hold him out for the rest of the season, according to Ian Rapoport of NFL Network.

EDGE Analysis

McCown has already been ruled out for Sunday's game against the Titans, though with Drew Brees healthy, he wasn't likely to get much playing time anyway. Rookie Garrett Grayson is expected to be the backup Sunday, and likely the rest of the season if McCown is ruled out.
