Back for the Ospreys scrum penalty and Walsh sets up an attacking lineout

Quick hands to Ratti on the right

Good hit up from Boshoff

Ospreys have advantage

Throw not straight, scrum Ospreys

Stoppage in play

Holding on and Ulster win the penalty near their own line, Murphy finds touch

Pick and drives edging forward

Morgan-Williams has a snipe

Ospreys keep it tight
