WORCESTER Warriors back-rower Caleb Montgomery may require surgery to fix his troublesome wrist.

The 24-year-old Irishman, a summer signing from Ulster, has played twice in the Premiership Cup, marking his Warriors debut with a try in the win over Leicester Tigers before producing another impressive display against Exeter Chiefs two weeks later.

But Montgomery has not figured in the Gallagher Premiership and an injury to his wrist has denied him a chance of making his league bow at Harlequins on Saturday (3pm).

“We have got to see the specialist and see what we do,” said director of rugby Alan Solomons.

Asked whether Montgomery needed to undergo an operation, Solomons added: “The wrist has been bothering him.

“We have to make a decision on when we do something about it.”

With Mongomery ruled out and flankers Sam Lewis (concussion) and Marco Mama (leg) struggling Warriors' back row options have been reduced for their meeting with Quins at The Stoop.

But Solomons said he could call upon Matt Cox who missed the start of the season through illness and Matti Williams who has overcome an arm injury.

“Matty Cox is back in full training and Matti Williams is about enter full training so we are not too bad,” Solomons said.

“Tom Dodd is also back so now we are better stocked.

“Caleb is a good, young player but his wrist has been bothering him for a while now so we have had it looked at and then a decision has got to be made.”
