ADELAIDE skipper Taylor Walker won't play again this year, accepting a two-game suspension that caps off his frustrating season.

Walker was handed a two-game ban for a tackle that knocked out Greater Western Sydney star Josh Kelly in last Saturday night's 14-point loss to the Giants at UNSW Oval in Canberra.

The defeat ended the Crows' chances of making the finals ahead of their remaining games against North Melbourne and Carlton.

Walker has had an injury-interrupted season and said it would be a good chance for him to sit out the last two games, while giving others a chance in his place.

"I'm not going to challenge it – it probably sums up my season," Walker told Triple M on Tuesday morning.

"It's been very challenging for me individually and us as a footy team.

"I'll just cop it.

"My body's crying out for a bit of rest at the moment, so it gives opportunity for someone else to play the last two games."

Walker said he thought he could be in trouble when Kelly had to be helped off the ground, and didn't take any further part in the game.

"It does happen so quick, and I do remember getting emotional thinking, 'S---, this could be a sling tackle', so I let him go," Walker said.

"But they're just so protective of the head and if the consequence is that they're knocked out, or hit their head, then you're in trouble.

"It's disappointing, but that's just the way the rules go."
