ADELAIDE winger Paul Seedsman says there's a "very real possibility" his AFL career could be over because of concussion.
Seedsman was concussed at training last December and won't play this season as he battles ongoing effects.
The 30-year-old says improvement in the past three months has lifted his hopes of a full recovery and playing next year.
"There was a time there where I couldn't see the light at the end of the tunnel, for sure," Seedsman told reporters on Friday.
"And I probably did think that I had played my last game ... it was just so frustrating and flattening each day, it was a battle.
"You hate the thought of it (not playing again) and I try not to spend too much time thinking about it. I understand that is a very real possibility.
"But everything I am doing in between is getting back to play."
Seedsman, who finished third in Adelaide's club champion award last season, suffered constant migraines and nausea after copping a knock to the head in a marking contest at training.
"I am not out of jail in that sense by any stretch," the 132-gamer said.
"I still have limitations on everything that I do, even from just a mental capacity, day-to-day tasks."
Discussions with his wife and wider family would also determine if he played again.
"Eventually I want to start a family and have kids and I don't want to be sitting in bed and being miserable all day, every day," he said.
"That is definitely the number one priority, life after football.
"I want to play footy ... (but) I am not going to be stupid with it."
