LOCK Matthew Screech says Newport Gwent Dragons can't afford to be obsessed with righting the wrongs of Sale as they prepare to lock horns with Leinster in the Guinness Pro12, writes Chris Kirwan.

The 23-year-old is one of four players brought back into the XV following last Thursday's 38-5 defeat in Salford that saw the Sharks earn Pool Two top spot and a home quarter-final.

Director of rugby Lyn Jones brings Screech in for Cory Hill, Carl Meyer returns for Geraint Rhys Jones at full-back after missing his first game of the season with a tight hamstring, loosehead Boris Stankovich is preferred to Phil Price and Nick Crosswell comes in for Wales number eight Taulupe Faletau.

The squad have been hurting after the manner of the loss at Sale but so are Leinster, who were drubbed 51-10 by Wasps in the Champions Cup.

"You have to draw a line under it. You can use it as motivation to some extent but it's another day and it's another week," said Screech.

"We had been building with some good wins and performances and nobody was expecting a loss like that but we are through to the quarters and looking forward to Gloucester.

"We all know that we have good performances in us so we just have to get stuck into Leinster straight away, we can't let them get a foothold.

"We have to be 100 per cent from the off, we are all about dealing with Leinster now and not thinking about Sale."

Jones has gone with experience for the encounter with Leinster – Screech is the only forward younger than 27 with the pack having an average age of 29.

Hallam Amos gets the chance to push for a place in Wales' Six Nations opener in Ireland by starring on the wing after being released by Warren Gatland for more game time in his recovery from a shoulder injury.

Injuries in the back row mean that James Benjamin is poised to feature from the bench for the first time since the loss in Dublin in October.

Leinster are down to the bare bones because of international call-ups and injuries but can still call on South Africa full-back Zane Kirchner, powerhouse centre Ben Te'o and Ireland back rowers Dominic Ryan and Jordi Murphy.

They have some experience on the bench in the shape of hooker Richardt Strauss, scrum-half Isaac Boss and fly-half Ian Madigan.

The Dragons did the double over Leinster for the first time last season, winning in Dublin 16-14 and then 25-22 at Rodney Parade, but suffered a 37-13 thrashing at the Royal Dublin Society in October.
