Worcester v Gloucester: Teams

Up-and-coming flanker James Collins makes the starting line-up as Worcester prepare to face Gloucester in their Guinness Premiership derby clash on Sunday.

Collins plays at blindside and is one of four changes made by Director of Rugby Mike Ruddock as the Warriors prepare for this crunch clash in front of a massive crowd at the Sixways Stadium.

Former Gloucester player Chris Fortey is named at hooker and Academy product Callum Black is handed his first Guinness Premiership start at tighthead prop.

Speedster Miles Benjamin returns on the wing for Warriors with former New Zealand international Rico Gear moving to outside centre.

Fit again fly-half Matthew Jones is named among the replacements along with centre Alex Grove.

"The positive aspect of last week's visit to London Irish was that some of the younger players that came off the bench fronted up and showed their desire to be part of the team," said Ruddock.

"Players like Callum Black and James Collins did exceptional well and they are now rewarded with a deserved place in the starting line-up.

"Willie Walker will also play against his 'own club' and I'm sure he will be keen to point to prove."

Gloucester have made five changes ahead of the match.

Matthew Watkins will start at outside centre, shifting Anthony Allen to inside. The young Charlie Sharples is replaced by James Simpson-Daniel after recovering from a hip injury which he picked up against Bath in late February on the left wing.

Elsewhere, Apo Satala takes up the position of flanker whilst Luke Narraway replaces injured Gareth Delve at eight.
