49ers' Anthony Zettel: Signs with San Fran

Zettel agreed Wednesday with the 49ers on a one-year contract, Cam Inman of the San Jose Mercury News reports.

San Francisco will bring in Zettel to shore up its depth on the defensive line with multiple players in the position group battling injuries early in camp. Zettel will be a long shot to make the 49ers' roster coming out of the preseason.
