Adelaide veteran Andrew McLeod will have knee surgery, possibly ending his ambition to play 350 AFL games.

McLeod, who is expected to retire at the end of the season, needed to play every game this year to reach the milestone.

But the Crows said on Monday the 33-year-old would have an arthroscopy to examine his right knee on Tuesday.

The knee has long troubled the 339-gamer, who will miss Adelaide's trip to Tasmania to play Hawthorn on Saturday.

With the Crows having the following week off for the midseason break, McLeod's best case scenario is a round 13 return.

Key defender Nathan Bock is still battling a groin injury and unlikely to return against the Hawks.

And backman Phil Davis will miss up to three weeks after being knocked out in a collision with Fremantle ruckman Aaron Sandilands.

Davis, 19, also suffered a sprained shoulder but won praise from team-mates for courage in running with the flight of the ball.

"He didn't even look back once, his eyes were solid on the ball," midfielder Rory Sloane said on Monday.

The Crows prevailed over Fremantle in stalwart Tyson Edwards' last game, with Sloane an unlikely source of motivation.

The 20-year-old, playing just his fourth game, summoned Adelaide's players together at three-quarter time and demanded a fitting finale for Edwards.

"I had a quick little word," Sloane said.

"It was a bit of emotional stuff for Tyson's last game, and just having that extra effort in the last quarter.

"I just wanted to make sure it was there, especially for his last quarter of football."
