NEWPORT Gwent Dragons have changed six of their pack for tomorrow’s must-win European Rugby Challenge Cup clash with Worcester at Rodney Parade after being overpowered by the Warriors last weekend.

Dragons boss Kingsley Jones has responded to the 33-20 loss at Sixways by bringing in loosehead Sam Hobbs, hooker Rhys Thomas, tighthead Lloyd Fairbrother, lock Rynard Landman, blindside Nick Crosswell and openside Ollie Griffiths.

Tavis Knoyle gets the nod at scrum-half while Geraint Rhys Jones wears 15 for the first time this season with Tom Prydie moving to the wing.

Worcester make three changes with back row forward Marco Mama making his first start since September while loosehead Ryan Bower and tighthead Mike Daniels come into the front row.

The Dragons have to win all three remaining group games if they are to qualify for the knockout stages for a third successive season with Worcester followed by January games with Enisei at Rodney Parade and a trip to Brive in round six.
