Rams' lose starting defensive tackle

Posted by ESPN.com's Mike Sando

The Rams have lost starting defensive tackle Gary Gibson to an injured left leg.

I do not have details, but Gibson left on a cart. He's been a good player for the Rams this season and a bit of a surprise.

Gibson was leading Adam Carriker for the starting job even before Carriker went on injured reserve. Depth at tackle suffers if Gibson misses an extended period. The team already released Hollis Thomas, who signed with Carolina.
