Fullback Darrel Young’s playing status against the Giants is to be determined shortly before game time (Washington Post/John McDonnell)

Fullback Darrel Young tested his injured hamstring muscle, although not fully, during the Washington Redskins’ practice Friday. It remained unclear if he will be able to play Sunday night against the New York Giants at FedEx Field.

Young and Redskins Coach Mike Shanahan said the team will make a decision about Young’s playing status shortly before game time Sunday evening. Young missed Monday night’s loss to the San Francisco 49ers and didn’t practice Wednesday or Thursday.

“He took just a few reps,” Shanahan said after Friday’s practice. “We didn’t want to overdo it. But that’s a positive sign.”

Tight end Niles Paul filled in for Young when the Redskins needed a fullback Monday night. But Paul has been sick this week and remained absent Friday from Redskins Park. Shanahan said that if Paul plays Sunday night, he probably would be limited to a special teams role.

Young and Paul were to be listed as questionable on the team’s official injury report, Shanahan said. Rookie tight end Jordan Reed also was to be listed as questionable after missing one game due to a concussion. Reed said Thursday he expects to play against the Giants.
