Patrick Mannelly injured vs. Chargers

CHICAGO -- Participating in his 215th career game, Chicago Bears deep snapper Patrick Mannelly suffered a knee injury Sunday in the second quarter of the team's 31-20 win with the San Diego Chargers.

The Bears officially ruled Mannelly out of the game, and fullback Tyler Clutts was seen warming up on the sideline even though tight end Matt Spaeth is listed as Mannelly's backup.

Mannelly appeared to suffer the injury on Robbie Gould's point-after kick, which came after a Marion Barber touchdown run that put the Bears ahead 10-3 with 4:16 left in the first half.

Mannelly immediately limped toward the Bears' sideline, and athletic trainers began examining him. After several minutes of being looked at by athletic trainers, Mannelly walked to the locker room under his own power.

Since joining in the Bears as a sixth-round pick in 1998, Mannelly has played the most games in franchise history. Mannelly has undertaken long-snapping duties in all but three games of his career, handling 2,017 of 2,037 Bears snaps since 1998 coming into Sunday's game.

Mannelly was playing in his team-high 147th consecutive game.
