Still sporting a black eye, Adelaide co-captain Rory Sloane has been given the all-clear to take on Collingwood in Saturday's crucial encounter at Adelaide Oval.

Sloane sat out the second half of last Sunday's 10-point loss to West Coast in Perth with blurred vision as a result of friendly fire from teammate Matt Crouch.

"I trained today and I feel good," Sloane said.

"I got my vision back, the sharpness back, the Monday after the game.

"I've had a few eye injuries before, which I suppose in that situation we were in, we had to wait and see if it came back fully, my vision."

Sloane has been cleared of any structural damage after getting checked out by a specialist on Monday afternoon.

"I've had a torn retina in that eye before and I've busted this eye socket, so we had to look after it," he said.

"With a normal whack in the eye, that blurriness should go in about five or 10 minutes, but mine stayed there and got a little worse as the game went on.

"The medical staff made a good call because the blurriness got worse as the night went on."

SANFL FIXTURE: The Crows' run home

Fellow co-captain Taylor Walker didn't train on Thursday as the club manages his training loads heading into a six-day break, but Sloane said Walker wasn't in any doubt for Saturday's game.

Alex Keath trained well after missing the past three games with a lingering ankle injury.

"He's good and he trained pretty sharp," Sloane said.

"We'll wait until this afternoon to see if they (the match committee) want to pick him or not.

"He hasn't played in a few weeks, but very handy footballer."

The ninth-placed Crows (10-10) are outside the top eight on percentage and would be unlikely to make the finals if they lost to the Magpies.
