ADELAIDE captain Taylor Walker has allayed concerns over a lingering foot injury, declaring himself a certain starter for the Showdown against arch rivals Port Adelaide.
Walker returned to Adelaide wearing a protective moon boot after the Crows' season-opening loss to North Melbourne at Etihad Stadium last Saturday night.
Walker said on Wednesday he had been troubled by a sore foot for the past month but was in no doubt to front against the Power in Saturday's clash at Adelaide Oval.
"I'm just trying to get a bit of weight off it early in the week," he told reporters.
"We have got our main session today; I will do the full session.
"It won't affect me at all ... I have had a bit of a sore foot for over a month or so now and Etihad is probably the hardest deck that we play on."
The Crows enter the Port clash after slipping to a 10-point away loss to North Melbourne that Walker blamed largely on ill-discipline.
Adelaide conceded some costly 50m penalties, one of which led to a goal after Scott Thompson was penalised under the new 10m protected zone rule.
"There were some things that we could control that we will change in critical moments," Walker said.
"We understand we played some really good footy against North but not quite good enough.
"There were a couple of 50m penalties with the new rules that we are still trying to get a grasp on.
"But if we can fix those up, there's a few things that will help us."
Midfielder Matt Crouch avoided sanction for his high hit on North's Jarrad Waite while Cam Ellis-Yolmen and Ricky Henderson are among players pressing for selection after strong SANFL games.
