DUNCAN Roke is out of Worcester Rugby Club's Powergen Cup tie at Wakefield this weekend.

The full back injured a knee in Saturday's league clash with the Yorkshiremen and looks set for two weeks on the sidelines.

Worcester are facing an injury crisis ahead of their fifth round clash at College Grove with a number of players doubtful for the weekend.

Wing Daren O'Leary has a dead leg, fly-half Tommy Hayes is still troubled by his rib injury, while prop Neil Lyman is struggling with a groin strain.

Centre Duncan Murray, who pulled out of Saturday's Wakefield game at the last minute because of a leg injury, is also facing a race against time to be fit, while Gary Trueman has a shin problem.

Flanker Christian Evans is also still out of action following an injury to his elbow.

"We're hampered by these injuries but we're still hopeful of putting out a strong side," said Worcester's director of rugby John Brain.

Werner Swanepoel and Richard Bates ould be in contention after battling knee injuries.
