Ulster started that half brilliantly with Irish internationals Jacob Stockdale and Cormac Izuchukwu to the fore.
With the former in the sin bin, they'll have breathed a sigh of relief that Makazole Mapimpi's second "try" of the half was chalked off as a one-score lead would have felt scant reward for their efforts.
What a fantatsic 40 minutes. They have been exceptional and played some brilliant rugby. Going up against a Springbok front row, Ulster's set play has been fantastic.
