Michael Vick will start on Sunday against the New York Giants, unless his injured left hamstring prevents the quarterback from reclaiming the No. 1 job with the Philadelphia Eagles.

NFL hearing officer Ted Cottrell has reduced the suspension of Washington Redskins safety Brandon Meriweather from two games to one.

The Washington Redskins have re-signed free agent safety Jordan Pugh just a week after he was released. Terms of the deal were not disclosed.
Pugh played in 16 regular-season games and one play-off game in 2012 and 2013 before his release on October 15 as part of the Redskins' push to upgrade their special teams. He has seen action in three games this season but does not have a tackle.
Jason Campbell is in and Brandon Weeden is out as the Cleveland Browns' starting quarterback.
Browns coach Rob Chudzinski said he is turning to the veteran Campbell for Sunday's game against the Kansas City Chiefs in place of Weeden, who struggled after Brian Hoyer went down with a season-ending knee injury in Week 5.
Campbell, 32, last started a game for the Chicago Bears in a loss to the San Francisco 49ers in November 2012. He becomes the Browns' 20th starting quarterback since 1999 and the team's third in 2013 as the season reaches the halfway point.

The St. Louis Rams have added two quarterbacks to their roster when they brought back Austin Davis and signed veteran Brady Quinn.

Josh Freeman's first game as the Minnesota Vikings' starting quarterback did not go so well on the field, and the team announced he suffered a concussion that could keep him out of Sunday night's game against the Green Bay Packers.

The New York Giants have placed centre David Baas on injured reserve with a knee injury suffered in Monday night's win over the Vikings.
