West Coast coach Adam Simpson has launched a stunning attack on Optus Stadium, blaming the venue’s controversial surface for injuring his players and vowing to stop training there.

The Eagles recorded their heaviest defeat at Optus Stadium in the 13.17 (95) to 8.5 (53) hammering from Port Adelaide, which could have consequences at the selection table next week.

It came after defender Tom Barrass was withdrawn pre-match with a potentially serious foot stress fracture. Simpson labelled Barrass a “victim” and blamed the stadium’s turf.

“Our list is pretty healthy, but whenever we lose a player it seems to be a lower-leg injury,” he said.

“So we’re assessing whether it’s another stress-related injury, which will be probably our seventh in the last 20 games. So we’re trying to work out why and we think we know where it’s pointing. We’re going to have to stop training here. That’s pretty obvious.

THREE-WORD ANALYSIS OF EVERY EAGLE: Have your say

“Let’s not take away what happened tonight. We got touched up and we got beaten by a better side who out-hunted us and it had nothing to do with how hard the ground is.

“But Barrass is an issue and we need to work through that. We’re working really hard behind the scenes but unless I get up here and talk about it nothing happens.”

It is the second time this season a tall Eagles outfit has been taken apart in greasy conditions, following their comprehensive season-opening defeat to Brisbane at a humid Gabba. West Coast have played an extra tall forward this season with the inclusion of youngster Oscar Allen as well as carrying two genuine ruckmen.

“We’ll look at it. We’ve got 15 or 16 night games this year, so if we can’t play in slippery weather we’re going to be in strife. So I hope it’s a bit deeper than that,” Simpson said.

“We’ve had a fantastic ride but this year is a new year and we need to understand, all of us, that we haven’t stamped our authority on this season.”

The 42-point loss to an inspired Power, who were $4 outsiders, also ended a run of 16 consecutive wins for the Eagles when key forwards Josh Kennedy and Jack Darling play together.

Darling, one of the best players in the competition this time last season, went goalless and received an ironic cheer from fans when he took a mark late in the third term. Youngster Jack Petruccelle kicked five goals including his team’s entire first-half score of 2.2.

Now 3-2, West Coast will have a nine-day break to regroup before facing ladder leaders Geelong at GMHBA Stadium next Sunday.

Perth’s first Good Friday AFL match attracted a solid crowd of 49,290 despite rain and the Easter long weekend, but fans were flooding the train station by three-quarter time.

The game was over as a contest by half-time, after the Power kicked nine goals to two in the opening half to surge to a commanding 49-point lead.
