Regular BT Sport pundit Austin Healey was in no doubt that Dan Biggar should have been given his marching orders.
He posted on social media: "How the hell has Biggar not got red for that?"
Ugo Monye added: "Yeah, it's a red." However, referee Dickson saw things differently, judging that Biggar had initially made contact with the ball that was tucked in Radradra's chest before rising up, which is why he only awarded a penalty."

Jonny Wilkinson picks top three stadiums he played in
Check out Wilkinson's favourite stadiums by clicking here.
#3. Stade de France (France)
Perhaps not the best situated stadium, but it sure has a great view. It's atmosphere can be a help and a hindrance for Les Bleus.
When France are on the front foot, it can generate a great atmosphere but it can also inspire the opposition when they’re not.
Wilkinson said: "‘Whenever I played there on every occasion, the atmosphere was fantastic."
#2. Principality Stadium (Wales)
The Old Cardiff Arms Park was great but everything about the Millennium Stadium – renamed later as the Principality Stadium – is nigh on perfect save from some early teething problems with the turf which can struggle a little when the roof is on for prolonged periods.
Wilkinson said: "I always felt Cardiff was an incredible stadium because of the passion and the knowledge the Wales fans have. I also won a Heineken Cup there, which I'll never forget."
#1. Stadium Australia (Australia)
Its capacity is 84, 000 and this makes it the biggest venue on this list
There are usually a minimum of two rugby union tests played at Stadium Australia over the course of a year, with one often being a tour match. Back in 2003, the stadium hosted seven Rugby World Cup games under its former guise of the Telstra Stadium.
Wilkinson said: "‘The best atmosphere I ever played in was in an England shirt was in Australia for that Rugby World Cup final, it was electric,
"Probably those three stadiums, they were brilliant."
