LB Donald Butler doubtful for Sunday

SAN DIEGO -- Donald Butler, the San Diego Chargers’ middle linebacker who has missed practice all week, was absent from Friday's practice and is listed as doubtful for Sunday’s game at Washington.

Butler missed the past two games with a groin issue. If Butler does not play, Andrew Gachkar will start in his place, with reserve linebacker Reggie Walker subbing in on passing situations.

Reserve offensive lineman Mike Remmers (ankle) also did not practice all week, and has been ruled out for Sunday. Receiver Eddie Royal did not practice at all this week because of a toe injury, and is listed as questionable.

However, Royal did not practice at all two weeks ago leading up to the Jacksonville game and he played. Royal wore a walking boot during practice this week.

“He came out, and he’s been working hard in what he needs to do,” San Diego coach Mike McCoy said. “And we’ll make that decision come game time with what we think is best for him.”

Offensive lineman Chad Rinehart was a limited participant again on Friday, and is listed as questionable with a toe injury. Rinehart hasn’t played in a month, but could see some time against Washington, although Johnnie Troutman likely will continue to start at left guard.

“He looked good,” McCoy said about Rinehart. “He got better every day. As the week went on, he got more and more comfortable. I think when you’ve missed the time that he’s missed, it’s just a matter of getting back out there and doing it again.”

Safety Eric Weddle (toe), defensive end Lawrence Guy (toe) and outside linebacker Jarret Johnson (hamstring) were full participants on Friday, and are listed as probable for Sunday’s game.
