The Bulls were beaten for the second time in New Zealand
Not even two tries from Springbok wing Akona Ndugane could save the Bulls from slumping to their second successive Super 14 defeat in New Zealand.
Having lost their unbeaten record against the Highlanders the previous weekend, the Bulls were beaten 16-13 by the Crusaders in Christchurch.
Not even the return to fitness of Victor Matfield and Bryan Habana could help the Bulls' cause and they have now lost their grip on the top spot as the Waratahs, Chiefs and fellow South African side the Sharks march on.
Having slipped 10 points behind in the first-half, the Bulls managed to level the scores at 13-13 on the hour with a penalty from Morne Steyn.
But it was a short-lived moment of glory for the visitors as Stephen Brett with a penalty in the final quarter to give the former champions the victory.
