Chargers place Rich Ohrnberger on season-ending IR

The San Diego Chargers' offensive line has taken another hit, as a back injury saw center Rich Ohrnberger placed on season-ending injured reserve Tuesday. 

With both Nick Hardwick and Doug Legursky already out for the year, Ohrnberger is now the third Chargers' center to have his season brought to an early end.

In a corresponding roster move, the team signed linebacker Cordarro Law from the practice squad.
