Riley Reiff’s chances of returning from injured reserve took a hit Thursday.

The veteran offensive lineman did not participate in the Patriots’ latest practice, according to Thursday’s injury report.

Reiff, who can play tackle or guard, was limited in the previous several practices as he works his way back from a knee injury.

The 34-year-old initially injured his knee during the preseason, then landed back on IR in October after appearing in one game. Reiff returned to practice during the Patriots’ bye week and must be added to the 53-man roster by next Wednesday. If he’s not, he would revert to season-ending IR.

Reiff was one of three nonparticipants in Thursday’s practice. Rookie wide receivers Demario Douglas and Kayshon Boutte also were sidelined.

Douglas is in concussion protocol after taking a hit to the head in last week’s loss to the New York Giants. He also missed Wednesday’s practice, putting his status for Sunday’s matchup with the Los Angeles Chargers in doubt. Boutte, who was limited Wednesday, missed practice due to a shoulder injury and an illness, according to the team.

Running back Ty Montgomery was a full participant after sitting out Wednesday with an illness. Nine players were limited:
