PACK duo Matt Kvesic and Ed Shervington will both make their 50th appearances for Worcester Warriors when the club faces USA Perpignan in the Amlin Challenge Cup at Sixways tomorrow night (7.45pm).

Hooker Shervington and flanker Matt Kvesic both hit the milestone as head coach Richard Hill makes just one change to the side that faced Harlequins last Friday.

Scotland international prop Euan Murray makes his first start for Warriors as he comes into the front row with John Andress among the replacements.

Hill admitted the game was crucial to Worcester's hopes of progressing in Europe this season and he expects an exciting game in front of the television cameras.

"It is a really exciting game and on the back of two very good league performances we are in a positive frame of mind," he said.

"We are desperate to get into the quarter-finals and we are top of the group at the moment. But we know we have a really tough task against a powerful French team.

"They have a quick turnaround as they travel over today and play tomorrow night, so we have got to hit them with everything we can in this first game. If we can get a win in this one, it puts us in a strong position for the second game the following week."

Perpignan have named a power-packed side for the Sixways clash with French international prop Nicolas Mas captaining the team from the front row and Wales interntional James Hook at fly-half. A strong back row includes former King’s School Worcester pupil Luke Narraway, Alasdair Strokosch and Henry Tuilagi.
