Offensive guard Rich Ohrnberger on the sidelines during the Arizona Cardinals' NFL preseason game against the Oakland Raiders on August 17, 2012.
The Chargers added another offensive lineman on Thursday. Rich Ohrnberger signed a 1-year contract.
Ohrnberger was a 4th-round pick of the Patriots in 2009. He played in just five games his first two seasons, seeing time at right guard and on special teams.
He missed all of 2011 with a head injury, was released and caught on with the Cardinals, where he played in 13 games on the line that gave up an NFL-worst 58 sacks last year.
Ohrnberger hurt his knee in December and missed the rest of the season.
During his senior year at Penn State, the 6'2", 300-pound Ohrnberger was a third-team All-America selection, so there is potential there. With the way the Chargers line has been decimated by injuries and defections, the new guy might have a chance to earn a starting spot.
Of the six unrestricted free agents the Chargers have brought in from other teams, three are offensive linemen.
