Chargers' Jerry Attaochu, Rich Ohrnberger back at practice

SAN DIEGO -- Two players who have missed the past two games for the San Diego Chargers were back at practice on Wednesday.

Rookie outside linebacker Jeremiah Attaochu was a limited participant. The Georgia Tech product missed the past two games with a hamstring injury, but is working to get back on the field for this Sunday’s game against AFC West rival Oakland.

The Chargers could use the depth at outside linebacker with Melvin Ingram on the injured reserve list/designated to return with a hip issue. Dwight Freeney played in a season-high 47 snaps against the New York Jets.

“It was definitely good to get back out there, out there with my teammates,” Attaochu said. “That’s the biggest thing -- just being back out there and practicing.”

Rich Ohrnberger missed the past two games with a back issue. Doug Legursky started in his place. However, Legursky suffered a knee injury late in the game against the Jets last week, and was placed on season-ending injured reserve.

If Ohrnberger can’t go on Sunday, rookie Chris Watt would be in line to get his first career start at center.

“I'm doing what I can to get out there,” Ohrnberger told reporters on Monday. “There's improvement every day. Obviously with any injury the more you’re working it, the better you’re feeling. So it’s heading in the right direction.”

Along with Ohrnberger and Attaochu, others who were limited on Wednesday include receiver Keenan Allen (quad), receiver Malcom Floyd (calf), outside linebacker Cordarro Law (ankle) and safety Darrell Stuckey (quad).

Players who did not practice for San Diego include inside linebacker Manti Te’o (foot), running back Donald Brown (concussion), outside linebacker Jarret Johnson (back, ankle), running back Ryan Mathews (knee), linebacker Reggie Walker (ankle) and cornerback Shareece Wright (knee).

The Chargers also made two minor roster moves, bringing back safety Adrian Phillips and adding UCLA product cornerback Aaron Hester to the practice squad.

San Diego filled a vacant spot on the practice squad created when cornerback Greg Ducre signed with Washington. The Chargers also placed running back D.J. Adams on the practice squad/injured list.
