Giants O'Hara Misses Third Practice In Row

EAST RUTHERFORD, N.J. (AP) — Giants Pro Bowl center Shaun O'Hara has been listed as doubtful for New York's home game against the Tennessee Titans after missing his third straight practice with ankle problems.

Adam Koets would replace O'Hara on Sunday and make his first career start as a lineman. He started last week as an extra tight end.

Defensive captain Justin Tuck also missed Friday's workout with a shoulder injury, but said he will play.

Giants coach Tom Coughlin says special teams captain Chase Blackburn is questionable with a knee injury and that backup safety Michael Johnson is out with a back issue.
