Injuries dictate 49ers' roster move

Posted by ESPN.com's Mike Sando

The 49ers signed receiver Dominique Zeigler from the practice squad Saturday, a move that helps with depth while Arnaz Battle recovers from injury.

The team released tackle Kirk Barton to make room on the roster for Zeigler. Releasing Barton became easier once the 49ers declared tackle Jonas Jennings healthy enough to serve as the swing tackle against the Cardinals on Monday night.

Note: Roided-out rosters now updated to reflect this move.
