Umaga fumes at swinging arm
Umaga's famous outburst to referee Peter Marshall came after being penalised for a dangerous tackle on Dan Carter during a 2003 Super Rugby match between the Hurricanes and Crusaders.
Now coach of the Blues, Umaga was fuming when Crusaders prop Owen Franks escaped with a caution when caught striking Blues hooker James Parsons with a swinging arm.
"I'm sure there are protocols around contact with the head," said Umaga. "That's the fact about it. First and foremost safety of our players is what we're looking for."
Franks was cited after the match for a dangerous tackle and copped a two-week suspension.
The Crusaders won the match 32-24.
The Blues have a bye in Round 15, while the Crusaders welcome the Hurricanes to Christchurch.
