Chargers place Rich Ohrnberger on IR

SAN DIEGO -- After he's dealt with a nagging back issue for most of the season, the San Diego Chargers finally brought center Rich Ohrnberger's season to a conclusion, placing the Penn State product on the season-ending injured reserve.

U-T San Diego reported that Ohrnberger will have surgery to correct the issue. The Chargers now have placed three centers on injured reserve this season in Nick Hardwick (neck), Doug Legursky (knee) and Ohrnberger.

Rookie Chris Watt started in place of Ohrnberger last week against the St. Louis Rams and played well. The Chargers selected Watt in the third round of this year’s draft as a potential long-term replacement for Hardwick at center, and the Notre Dame product will get a chance to prove his worth for the rest of the season with Ohrnberger out.

With a vacant spot, the Chargers signed outside linebacker Cordarro Law from the practice squad to the active roster.
