Wide receiver Pierre Garcon is back at full speed during the Washington Redskins’ practices, Coach Mike Shanahan said Friday.

Garcon was a limited participant during Wednesday’s practice because of a calf injury but returned to full practice participation Thursday. Shanahan said after Friday’s practice that Garcon was to be listed as probable on the official injury report for Sunday’s game against the San Diego Chargers.

Quarterback Robert Griffin III and safety Reed Doughty also are to be listed as probable.

Griffin is expected to play after being knocked from last Sunday’s loss at Denver because of an injury to his left knee. Griffin said at the time he could have finished the game if needed. He practiced fully all week and Shanahan called the injury a non-issue.

Doughty missed the Denver game because of a concussion.

Reserve safety Jose Gumbs is listed as questionable because of a sore ankle.

Defensive end Stephen Bowen (knee and shoulder), nose tackle Chris Neild (calf), wide receiver Leonard Hankerson (foot), tight end Logan Paulsen (knee) and running back Chris Thompson (shoulder) are listed as probable on the injury report.
