WEST Coast ruckman Scott Lycett will have latarjet surgery on his dislocated left shoulder and is likely to be sidelined for up to three months.

Lycett, 24, suffered the injury to his left shoulder in his comeback game playing for East Perth in a WAFL practice match.

Fremantle superstar Nat Fyfe, his teammate Garrick Ibbotson, St Kilda midfielder Luke Dunstan and Gold Coast champion Gary Ablett are among several AFL players to have undergone the latarjet procedure in recent seasons. 

The recovery time for all those players was about 12-14 weeks, or three months.

West Coast football manager Craig Vozzo told the club website Lycett would be operated on next week.

"He's going to require surgery. There was a dislocation, which has caused some bone damage," Vozzo said.

"The extent of the damage was such that we're not going to take the risk on a conservative treatment.

"Our doctors are recommending that we go down the path of latarjet surgery, so that will take place early next week." 

Lycett spent much of the pre-season in rehab after the posterior cruciate ligament in his left knee operated on at the end of last season.

Star big man Nic Naitanui is set to miss most of the season as he recovers from a knee reconstruction.

Lycett's fellow Eagles ruckman Jonathan Giles had 49 hit-outs for East Perth in the practice match, 15 of which went to advantage. However, recruits Nathan Vardy and Drew Petrie appear to be ahead of Giles in the pecking order after both put together impressive campaigns in the JLT Community Series.

Meanwhile, a stress reaction in draftee Jake Waterman's right foot will keep him out for at least two months. 

"Jake Waterman has suffered a stress reaction in his foot, in the mid-foot area, which we're going to treat quite conservatively," Vozzo said.

"It'll require him to be in a boot for a period of time, and then a graduated build-up. About an 8-10 week period before he's ready to play. 

Waterman is the son of dual premiership Eagle Chris.

Tall forward Matthew Allen was hurt in the same practice match as Lycett, with his right hamstring failing on him again. He will miss at least two weeks. 

"Because it's the second time it's occurred, we're going to treat it quite conservatively and build him back up," Vozzo said.

"I haven't got a recommendation yet as to what the period of time out is going to be, but it will be at least a couple of weeks."
