Ospreys v Connacht:OSPREYS ARE the only club, aside from Munster, to have won their first four games of the season. While Connacht have had their best ever start with three out of four wins, this match will be a litmus test for the ambitious side.

Coach Eric Elwood has opted to keep his back line unchanged with Gavin Duffy captaining from fullback, Eoin Griffin and Henry Fa’afili in the centre and Brian Tuohy and Tiernan O’Halloran on the wings. The halfback pairing of Frank Murphy and Niall O’Connor remains.

Dylan Rogers replace Rodney Ah You at tighthead, while Michael Swift has recovered from illness and returns to the starting line-up, Dave Gannon moving to the bench.

The other change in the pack sees 28-year-old Magherafelt-born former Ulster player TJ Anderson make his competitive start for the province at blindside flanker.

An unlikely win at the Liberty Stadium would allow Connacht leapfrog the Welsh region and into second place on the table. Connacht, however, must first get over the thorny issue of not having won on Ospreys soil since 2004.
