Adelaide look set to lose star forward Kurt Tippett for at least one game after he suffered his third concussion in a month in the Crows’ 49-point win over West Coast in Adelaide.

The injury soured Adelaide’s impressive performance with Bernie Vince kicking four goals in his 100th game as the Crows won 19.10 (124) to 11.9 (75).

Tippett went down in a clash of heads with Beau Waters at the 22-minute mark of the second term.

He warmed up after the half-time break and returned to the bench but was subbed out of the game midway through the third term without taking to the field.

Tippett had only just come back to the side after missing Adelaide’s win over Greater Western Sydney last weekend because of his second head knock of the season.

Coach Brenton Sanderson said he didn’t think the incident looked too bad but the club would take no chances.

He said he would be guided by the opinions of his medical team and would probably get some external advice.

“If he’s not right to play, then he won’t play, it’s as simple as that,” Sanderson said.

“Kurt’s had no concussions in his life and then he has three in four weeks.

“It’s hard to know why, it’s just unlucky.”

With four goals and 25 possessions, Vince was the standout for the Crows who stunned the Eagles with a six goals to one opening quarter for a 33-point lead at the first break.

But there was plenty of support from the likes of Rory Sloane, Patrick Dangerfield and Scott Thompson.

Returning veteran Graham Johncock was pushed into the forward line and kicked two majors while Jason Porplyzia kicked three.

The Eagles had some solid contributors including Daniel Kerr, Scott Selwood and Matt Priddis, while Nick Naitanui and Dean Cox won the hit-outs.

But a string of turnovers cost the visitors, allowing the Crows some easy scoring opportunities and coach John Worsfold was concerned at how Adelaide dominated the clearances despite losing the ruck contest.

“We’ve been smashed in the scores from stoppages the last two weeks,” he said.

“It’s an area we have to address.”

Adelaide’s win cements the Crows’ spot in the top two on the AFL ladder and makes West Coast’s bid for a similar finish that much more difficult.

Worsfold rejected suggestions his side’s season was slipping away but admitted it might take six wins from their last six games for the Eagles to finish first or second.
