West Coast midfielder Sharrod Wellingham is certain to miss Saturday’s clash with Adelaide and could be sidelined for the rest of the season with a serious knee injury.

Wellingham was helped from the field during the third quarter of East Perth’s 21-point win over West Perth in the WAFL on Saturday.

Scans later revealed Wellingham had damaged the lateral meniscus of his right knee while battling in soggy conditions at Medibank Stadium, with West Coast still to make a decision on possible surgery for the 26-year-old midfielder.

The former Magpie has played 13 matches in two seasons at West Coast, with just three appearances for the Eagles in 2014.

Meanwhile, Luke Shuey has escaped a serious ankle injury but remains in doubt to face Adelaide on Saturday at Adelaide Oval.

Shuey was carried from the ground after collapsing on his left ankle during the third term of the Eagles’ loss to Richmond last Friday night.

He returned to the action in the last quarter but was clearly under physical duress. Shuey had his ankle heavily iced post-match and was on crutches on Saturday morning. The tough 24-year-old will face a fitness test later in the week.

Ash Smith also suffered a thigh injury in the loss to Richmond and is another Eagle who will have to pass a fitness test before lining up against the Crows.
