Late try a bonus for Ulster
But it was his replacement Ruan Pienaar who put the icing on the cake when he scored the bonus-point try in the last play of the game.
It looked as if Ulster had tossed away the chance of a five-pointer when they scored their third try as early as the 43rd minute. But a last-gasp interception by Jared Payne in his own 22 allowed Paddy Jackson, Darren Cave and Pienaar to inter-change passing before the Springbok charged over under the posts with an exhausted Castres defence left breathless.
