Decorated Adelaide duo Simon Goodwin and Andrew McLeod may not play AFL again, Crows coach Neil Craig says.

Goodwin and McLeod are battling injuries which are ruining the end of their stellar careers.

Goodwin and McLeod are battling injuries which are ruining the end of their stellar careers.

Crows captain Goodwin has missed the past three matches with an achilles injury.

McLeod, the club's games record holder with 340 matches, has played just one of the past eight matches following knee surgery.

Goodwin, a 275-game veteran, announced in May he would retire at season's end and McLeod is tipped to follow.

With just two matches remaining after Adelaide's trip to Brisbane on Sunday, Craig concedes the clock is ticking on their careers.

"They are still a way from playing," Craig said on Friday.

"Every game they are missing out is going to make it more and more difficult.

"Those two guys ... one of the reasons they have been such fantastic players is because of their great pride in their performance.

"I guarantee you, what they won't want to do is put themselves out there if they can't actually take the game on." McLeod, 34, ran on a treadmill on Friday and Goodwin, 33, has discarded a protective 'moon' boot around his troublesome achilles.

Craig dismissed the notion of the pair, both five-time All Australians, playing a farewell match at home in the final round.

"Simon is not interested in standing in a forward pocket with a moon boot for a farewell game, that doesn't interest him one little bit" he said.

"And I know Andrew is of the same sort of thinking.
