WEST Coast big man Fraser McInnes appears set to miss the rest of the season after badly damaging his hamstring in the WAFL on the weekend.

McInnes made his AFL debut earlier this year against the Brisbane Lions in round four and played seven games before being squeezed out with the return of star forward Jack Darling.

The 22-year-old had continued to perform well for East Perth in the WAFL and kicked four goals in a dominant display on Saturday before injuring his hamstring.

The full extent of the damage is not yet known, but Eagles' football manager Craig Vozzo told the club's website it is likely to be a long-term injury.

"We're getting it assessed at the moment with the surgeon, with possible surgery to follow," Vozzo said.

"So we'll know more about that in the next few days, but it's looking like a longish-term injury at this stage."

Key defender Will Schofield is a chance to play this week after suffering a calf problem on Sunday in the win over the Sydney Swans.

Vozzo said Schofield is moving well but he will be tested later in the week given the Eagles have only a six-day break before facing Gold Coast at Metricon Stadium on Saturday night.

Jeremy McGovern won't play this week but is a chance to return for the round 19 blockbuster against Hawthorn, as he continues to recover well from the hamstring injury he suffered against Collingwood.
