There was off-the-ball pushing and a suspicion of a foot trip. There was blood streaming from first-five Bernard Foley's face after he was grabbed in a tackle and constant attempts to physically and mentally undermine halfback Nick Phipps.
The Hurricanes tread a fine line against the Waratahs in Sydney with their aggression and willingness to goad their opponents in their 28-17 victory in Sydney at the weekend, and similar tactics against the Crusaders in Christchurch on Saturday could rattle a team who have lost to only New Zealand opposition this season.
Chris Boyd's team need to be wary that some of their actions to which New Zealand referee Chris Pollock, in his final Super Rugby match, turned a blind eye, might not be acceptable to another official. The pushing of Phipps over the sideline by wing Julian Savea was deemed okay despite it appearing to be an attempt to intimidate, and it probably reached the threshold of at least a warning. Instead, no action was taken, and the niggle continued.
Pollock has form here this season - he was similarly nonchalant about some of the Highlanders' off-the-ball tactics which threatened to ignite into violence during the southerners' victory over the Crusaders in Dunedin - and Todd Blackadder's men won't be in the mood to take a step backwards in a match which will define their playoffs.
A defeat could send them to a quarter-final against the Stormers in Cape Town. Should they win that, they face a trip back to New Zealand and a possible re-match against the Hurricanes in Wellington, the travel factor adding to the difficulty of the assignment.
