"I think it sounds like it's a lot to ask right now, but we'll just see. I don't know. It's a serious injury," head coach Pete Carroll said in an interview with Dave "Softy" Mahler on Seattle's 950 KJR after practice on Monday.
McDowell traveled from Michigan to Seattle to officially report to the team last week after beginning training camp on the reserve/did not report list. He has since returned home to continue his recovery remotely. He was placed on the non-football injury list after reporting to the team.
"He had a serious accident. He had multiple injuries. He had an injury to his head. It's going to be quite a while and we're going to have to wait it out," Carroll told reporters.
"He's on (the non-football injury list) and is going to be there for a while and we're just going to have to see how he progresses down the road. We're not looking for him getting back in the immediate, not even for the first game of the season or that kind of stuff."
McDowell, who was the 35th overall selection in the draft out of Michigan State, sustained a concussion and facial injuries in the accident.
Carroll didn't elaborate any further on McDowell's injuries, saying that his family has made requests about how the information is being handled. The team is trying to comply with that request. Carroll said the injuries are not believed to be career-threatening.
"We don't think so, but we have to wait," he said. "He's just turned 21. We just got to wait him out. He's a real young kid, so he's got plenty of time to get well but we have to make sure and take care of him.
"Just got to wait out recovery. He's not working out yet; he can't do anything as far as physical workouts. He's walking is what he's doing. He feels fine. It's very frustrating for him because he feels fine but he's just got to make it through the recovery."
