Western Province played 55 minutes with 14 men and still battered the Bulls at Loftus.
Province won 29-18 to remain unbeaten in this year’s Currie Cup.
Province lost Michael Rhodes to a red card in the 35th minute for stomping, but the Bulls could not make the one man advantage count.
They lost a player to a yellow card and their discipline was simply not good enough.
Province goalkickers Kurt Coleman and Gary van Aswegen converted five of the kicks to punish the Bulls, who in the last minute of the match were denied a losing bonus point try through a TMO decision.
Blue Bulls – Tries: Jono Ross, David Bulbring. Conversion: Handré Pollard. Penalty: Pollard. Drop goal: Pollard.
