Washington Redskins wide receiver Jamison Crowder participated in practice Thursday for the first time in weeks, after missing the last four games due to an ankle injury. The team’s top slot receiver was limited, taking part in some individual drills, and Coach Jay Gruden said there would need to be significant progress for him to play Sunday.

“We’d have to see a pretty good day tomorrow out of him, like in team work and red-zone activity,” Gruden said.

The receiving corps also inched closer to getting another player back, as seventh-round rookie Trey Quinn returned to practice. Quinn had been on injured reserve since suffering an opening-week ankle injury that required surgery. The first day he’s eligible to be placed on the 53-man roster is Monday.

Tackle Trent Williams (thumb surgery), cornerback Quinton Dunbar (shin) and running back Chris Thompson (ribs) did not practice. Thompson was officially ruled out and Williams is expected to be out for two or three more weeks, while Dunbar’s status for Sunday’s game is unclear.

Right tackle Morgan Moses was limited and continued to wear a bulky brace on his right knee. Tight end Jordan Reed was also limited with a back injury.
