Robbie Diack wary of wounded Ospreys

So Ulster’s trip to Swansea to face a faltering Welsh outfit will see them either drop out of the race in the Guinness PRO12 play-offs or, in all probability, bring a trip to Dublin to meet their oft-nemesis Leinster in the semi-final.
With Leinster (79 pts) and Munster (76) having already booked the top two slots, fifth-paced Ulster (64) are battling with the Scarlets (67) and the Ospreys (65) for the final two places. Ulster also face Leinster in the final game of the regular season next week, while the Welsh teams square up to each other.
