ADELAIDE assistant coach Mark Bickley says defender Phil Davis is no certainty to return against Richmond this week, after being controversially left out of the team that lost to Port Adelaide on Sunday.

Davis earned a NAB AFL Rising Star nomination for his performance against Geelong in round 17, but was squeezed out of the side just a few days later to make way for centre-half back Nathan Bock.

Bock was rusty in his first game back from a groin strain but will be given an opportunity to regain form, meaning Davis could spend more time in the SANFL. 

Bickley said it would be another difficult week for the selection committee, with Chris Knights, Brett Burton and Trent Hentschel also available for selection.

“If you look at the guys that Phil plays in a similar position to, like Ben Rutten, Scott Stevens and Nathan Bock I don’t think any of those guys were outstanding on the weekend, but at the same time I’m not sure if you saw Phil play [in the SANFL] but he didn’t have his best game either,” Bickley said on Tuesday.

“It’s easy in hindsight to look back and think you should’ve gone another way, but at the time we made the decision we were comfortable with it because the structure we wanted down there had been a successful one and we thought we picked the best three players to play that.

“Phil will be desperate to get back in, so he’ll be up on the selection table and we’ll see how we go this week.”

Defender Graham Johncock will miss the clash with the Tigers, after accepting a one-match ban for rough conduct against Port Adelaide rookie Cameron Hitchcock.

Skipper Simon Goodwin is responding well to treatment on his injured achilles and could be available to play as early as this week.

Andrew McLeod’s recovery from an ongoing knee complaint has been slower, but Bickley said he expected both veterans to play again before the end of the season.

“We’re starting to see some improvement with Goody’s leg, so I’d be very surprised if he didn’t play again this year and Andrew’s the same,” Bickley said.

“Talking to both of those guys last week they were disappointed that they didn’t play on the weekend, but they weren’t giving any indications that they wouldn’t be playing again this year.”

The talk this week has been about the much-anticipated release of McLeod’s book, which details his falling out with former teammate Tyson Edwards.

Bickley denied the release of the tell-all book had had an impact on the club.

“There are going to be headlines each week and this week it’s about the book, but for us it’s old territory really,” he said.

“The players here have been aware for a long time of the situation so there’s nothing earth shattering in there that most blokes haven’t been aware of.”

The Power ended Adelaide’s four-game winning streak with an upset 19-point victory at AAMI Stadium on Sunday.

The Crows failed to hit top gear in the twilight clash, but Bickley said it was impossible to tell whether the lacklustre performance was a result of a letdown after the club’s big win over Geelong.

“There’s no doubt that the players experienced an enormous emotional high last week against Geelong…but they’ve certainly come back to earth this week and that’s all part of learning,” Bickley said.
