WEST Coast ruckman Scott Lycett's hopes of playing in round one appear all but over after injuring his left shoulder playing in a WAFL practice match. 

Making his return after a PCL reconstruction at the end of last season, Lycett dislocated his left shoulder laying a tackle in a practice match against East Fremantle.

The Eagles big man didn't return to the field after the second-quarter incident and the club is waiting on the results of scans to determine the severity of the injury.

Lycett played for East Perth hoping to prove his fitness ahead of the Eagles' round one clash against North Melbourne in 15 days' time.

But the 24-year-old big man now appears in serious doubt for the season opener in a further blow to West Coast's already-depleted ruck stocks.

Recruits Nathan Vardy (Geelong) and Drew Petrie (North Melbourne) have carried West Coast's ruck division in the JLT Community Series and are in the box seat to take on the Roos.

Fellow ruckman Jonathan Giles was left out of the Eagles' final pre-season hit-out against Melbourne on Thursday night as he recovers from an untimely thumb injury. 

Giles, young defender Tom Barrass, midfielder Jack Redden, running backman Will Schofield and midfielder Liam Duggan were all in East Perth's squad to face East Fremantle. 

The Eagles have another chance to take a look at players ahead of round one when the Royals play round one of the WAFL season against Fremantle-aligned Peel Thunder on March 18 – eight days before West Coast's round one clash.
