Boss and McCullough start for Ulster against Ospreys

The back row is transformed with Neil Best and David Pollock dropping out of the squad and Matt McCullough taking the number 6 jersey and former Irish International Kieron Dawson starting at 7.

In the front row Bryan Young returns to loose head with Justin Fitzpatrick omitted from the team and Declan Fitzpatrick added as cover. Grant Webb is named on the bench.

The backs remain unchanged apart from Isaac Boss returns to the starting lineup with Kieran Campbell acting as cover.

Williams said this of his team selection, "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. 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 3 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"

Ulster's next home match will see them face Connacht on 11th April.
