TEAM NEWS:  Matt Williams had the luxury of recalling Matt McCullough, Isaac Boss, Kieron Dawson and Bryan Young to the starting line up ahead of their visit to Swansea to take on the Ospreys tomorrow night.

With Neil Best and David Pollock dropping out of the squad, the new look backrow is transformed as McCullough takes the number six jersey and former Irish International Dawson starting at seven.

In the frontrow Young returns to loosehead in place of Justin Fitzpatrick with Declan Fitzpatrick acting as cover on the bench. Grant Webb is also named on the bench.

Boss returns in the only change to the backline with Kieran Campbell acting as cover.

"We have some guys back starting for us including Bryan Young, Kieron Dawson and Matt McCullough, we are fortunate that we have those options to move things around and keep things fresh," said Williams of his selection.

"Paul Marshall picked up an injury against Munster so Isaac will be starting. Our back line functioned well offensively against Munster and the off set play defended well so that unit remains the same with Kieran Campbell in as cover on the bench

"Grant Webb deserves a shot; I haven't seen him play since I arrived so it is an opportunity for him on the bench, same with Roger Wilson who has had 20 minutes of rugby in last three months.

"We know that this will be a tough game, we always said the Munster and Ospreys games would be the two hardest away games but it is a chance to give the young guys some game time and the game will be really important as part of the learning curve as we build up to the home Connacht game on the 11th April," added the coach referring to Ulster's next home game.
