McCall makes six changes
Ulster could do Munster and Leinster a huge favour if they topple The Neath-Swansea Ospreys in the Celtic League at St Helen's on Friday.
Coach Mark McCall has made six changes from the Heineken Cup loss to Cardiff Blues.
Bryn Cunningham and Tyrone Howe will give them a Ulster out wide. Rod Moore and Rory Best have been added to the front row, and Gary Longwell and Campbell Feather will give the side a fresh look to the spine of the pack.
Elsewhere, in the replacements, Shane Stewart, returning from a knee injury, is named in the 22 for the first time since the pre-season friendly against NEC Harlequins in August.
ULSTER (v Ospreys): Bryn Cunningham; Tommy Bowe, Paul Steinmetz, Kevin Maggs, Tyrone Howe; David Humphreys, Kieran Campbell; Simon Best, Rory Best, Rod Moore, Gary Longwell, Matt McCullough, Campbell Feather (Capt), Neil Best, Roger Wilson.
Replacements: Paul Shields, Ronan McCormack, Rowan Frost, Andy Ward, Reece Spee, Adam Larkin, Shane Stewart.
