Adelaide skipper Taylor Walker has confirmed will not challenge the two-match ban he was handed by the MRO, effectively ending his season.

The star forward was reported for his dangerous sling tackle on GWS' star midfielder Josh Kelly, leaving the silky Giant concussed.

MRO Michael Christian charged Walker with a two-match ban on Monday night, and with the Crows set to miss the finals, Walker will not feature again in 2018.

"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."

Kelly remains doubtful to play in GWS' clash with the Swans on Saturday at Spotless Stadium.

"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."
