Morgan Moses, the only member of the Redskins’ injury-ravaged offensive line to start every game this season, participated in individual drills Thursday after sitting out Wednesday’s practice. The Redskins’ right tackle has dealt with nagging ankle injuries all season, the latest of which caused him to be carted off the field during last week’s loss to the Cowboys. Moses’s status for Sunday’s game at the Los Angeles Chargers is uncertain.

“He’s out there and did some individual [work] today,” Redskins Coach Jay Gruden said Thursday. “Was very limited, but he’s making progress, which is a good thing.”

Gruden said he isn’t worried about Moses’s ankle injuries long term but suggested that the 26-year-old work on his ankle strength in the offseason.

Left tackle Trent Williams (knee), tight end Jordan Reed (hamstring) and safety Montae Nicholson (concussion) did not practice Thursday. Linebackers Zach Brown and Martrell Spaight, wide receiver Maurice Harris, center Chase Roullier and defensive tackle Terrell McClain were limited.

Defensive tackle Matt Ioannidis practiced for a second consecutive day without the bulky cast he has worn on his left hand for the past three games. The second-year pro missed two games after fracturing his left hand against the Cowboys on Oct. 29. “It’s good to see his fingers,” Gruden quipped.

Ioannidis had 3.5 sacks in seven games before the injury; he has been held without a sack in three games since his return.

“It restricts him a little bit,” Gruden said. “I think he would’ve had a sack last week, actually, but he escaped on his cast hand, which he couldn’t grab any cloth. It does have an impact without a doubt, but I think he’s been gutting it out and doing the best he can with what he’s had to work with and he’s been playing effectively, but just not quite as good as he would without it.”

Putting pressure on Chargers quarterback Philip Rivers will be important, but difficult, on Sunday. Rivers, who has thrown six touchdown passes without an interception during Los Angeles’s three-game winning streak, has been sacked only 13 times in 12 games.

“He knows where he has to go to the ball, just reading coverages and knowing who to spot, and just knowing where he wants to put the ball,” said Redskins defensive coordinator Greg Manusky, who knows Rivers well from his time as an assistant with the Chargers. “He’s very effective getting the ball out of his hands, and from a pressure standpoint, he knows where the pressures are coming. Over that long period of time that he’s been playing, he understands that and he does a great job with it.”
