Chargers signed G/C Rich Ohrnberger, formerly of the Cardinals, to a one-year contract.
Ohrnberger started four games, two at center and two at right guard, for the Cardinals last season before ending the year on injured reserve with a knee injury. The 27-year-old has appeared in 18 career games. At 6-foot-2 and 300 pounds, he's a good fit as a backup in the new zone-blocking scheme.
