FLORHAM PARK, N.J. (CBSNewYork/AP) — Josh McCown will start at quarterback for the New York Jets against the Buffalo Bills on Sunday in place of injured rookie Sam Darnold.

Coach Todd Bowles says Thursday he has ruled out Darnold to start because of a strained right foot, but hasn’t determined whether the rookie will be inactive for the game. If Darnold is out, Davis Webb would be promoted from the practice squad to serve as McCown’s backup.

The 39-year-old McCown has not taken a snap in a regular-season game this season as the Jets have focused on developing Darnold. The No. 3 overall pick won the job out of training camp, but was injured during New York’s 13-6 loss at Miami last Sunday.

McCown was the Jets’ starter last season and had a career year before being sidelined the last three games with a broken left hand.
