Warriors captain Simon Mannering will miss his first NRL match in more than two years after being ruled out Saturday's clash against Manly in Perth.
Mannering injured his right ankle late in last weekend's loss to Newcastle at Mount Smart Stadium, but club medical staff are optimistic he will be able to return for the encounter with Cronulla next weekend.
His absence has resulted in a career-first for winger Manu Vatuvei, who has been named to lead the side as he returns from his own injury-enforced one-week break.
"We're satisfied Simon isn't seriously injured but he'll be out this week," Warriors coach Brian McClennan said.
"It's a big loss for us obviously, because Simon does so much work and we're so used to having him out there every week and nearly always for the full 80 minutes.
