San Diego O-line taking major hits

Posted by ESPN.com’s Bill Williamson

OAKLAND -- The Chargers’ offensive line may be in trouble.

San Diego standout center Nick Hardwick was taken off the field on a cart. He has an apparent ankle injury. If Hardwick’s injury is serious, the Chargers will miss him badly.

A few plays earlier, San Diego guard Louis Vasquez left the game with a knee injury. He is questionable to return. He was replaced by Scott Mruczkowski. However, he is the backup center and he replaced Hardwick.

San Diego doesn’t have another interior offensive linemen active. Backup tackle Brandyn Dombrowskiis now playing in Vasquez’s spot.

Oakland guard Robert Gallery returned in the third quarter after leaving early in the game with a back injury.
