Referee Sam Grove-White gave Sharks flanker Dylan Richardson a stern talking too, as the back-rower was told off for appealing for a high tackle. Grove-White firmly told Richardson; "don't shout at me."
The incident took place after Ulster's Duane Vermeulen's tackle on Sharks' prop Hanru Jacobs. The collision was higher than a definitely legal tackle, which prompted an outburst from Richardson. The short video clip has since gone viral, racking up over 300,000 views across TikTok and YouTube.
"Listen to me. I've got a deliberate knock on but you can't shout at me like that."
The 30-year-old referee's instructions were clear, and got the rugby fanbase talking about his excellent control of the game. Rugby is a game built upon respect, with the referee's at the heart of the action.
You can hear Richardson apologising at the end of the video, as he wants to avoid a trip to the sin bin. "Sorry, I was just.... sorry, I'm sorry ref".
NIGEL OWENS: MY TOP 5 CAPTAINS
#5. Chris Robshaw (England)
Owens said: Some people will be surprised at this one to start off. His misfortune was perhaps to be leading England during a difficult time, but he always gave everything for the cause, encouraging others to follow suit, and he was a nice guy off the pitch."
#4. Jean de Villiers (South Africa)
Owens said: "He was not only a great rugby player but also a great leader and a great man. Whenever I came across him on the field, he impressed me."
#3. Richie McCaw (New Zealand)
Owens said: "He’s right up on any list of rugby’s greatest players.
"Maybe he will be at the top for many people.
"New Zealand won something like nine out of every 10 games in which he led them, but the mark of Richie McCaw was how he conducted himself when the All Blacks lost."
#2. Paul O'Connell & Brian O'Driscoll (Ireland)
Owens said: "I’m classing this as a joint-ticket as whenever I seemed to ref Ireland in their day O’Driscoll was captain and O’Connell was vice-skipper.
"O’Driscoll actually used to tell me if there were issues with the forwards then I should chat to O’Connell.
I found them excellent to deal with."
#1. Thierry Dusautoir (France)
Owens said: "My choice as the best skipper I encountered may raise a few eyebrows, but what a captain Dusautoir was. He unfailingly put his body on the line throughout his career — recall the 38 tackles he made when France knocked the All Blacks out of the 2007 World Cup — led by example and understood the game very well."
