Ulster are still waiting for their first win of the United Rugby Championship season as despite taking the lead against Stormers in Cape Town they slipped to a third defeat in five matches.

Yaqeen Ahmed scored 13 points as the hosts made it four successive bonus-point wins with a 33-7 victory.

Ulster, missing eight Ireland internationals, went ahead through David McCann, with fly-half Jack Murphy adding the conversion.

However, the visitors’ lack of discipline cost them as tighthead prop Keynan Knox was sin-binned for repeated infringements.

Stormers took full advantage with JD Schickerling and Paul de Villiers touching down to open up a 12-7 half-time lead.

Evan Roos’ superb solo try early in the second half paved the way for Ruhan Nel and Ahmed to extend their lead further.
