The New England Patriots have confirmed that they have placed offensive lineman Bryan Stork on injured reserve designated to return.
The 24-year-old sustained a concussion during his side's training camp and did not play a game during their pre-season campaign.
Bill Belichick's men have deemed the injury serious enough to place him on IR-return, ruling him out of action until week nine of the season.
The Patriots signed cornerback Justin Coleman from the Seattle Seahawks to take Stork's place on the roster.
