Devonta Freeman has been placed on injured reserve with a groin injury.
"Following the game against Pittsburgh, where Devonta injured his foot, we thought he was just having general soreness in his groin area," Quinn said. "As the week went on, it continued, so we decided to have him get some tests. It has been determined that he will need a procedure that will result in us placing him on injured reserve.
"We are hopeful he will be able to return this season, but we will have a better feel for that in the coming weeks."
A source told ESPN that Freeman has not yet scheduled the procedure.
Freeman played in just two of the first six games while slowed by knee, foot and groin injuries.
