WATCH: Keith Earls red carded for spear tackle, but not everyone agrees with the call

Did the referee make the correct call here?

Munster were handed an early blow during their Champions Cup clash against Glasgow Warriors in Thomond Park on Saturday. Keith Earls was shown red for a dangerous tackle on Glasgow hooker Fraser Brown after 18 minutes. https://twitter.com/eatsleeprugby/status/789805917311205376 Clearly unhappy with being taken out of the game so early, Earls let out his frustration by kicking a water bottle on the way to the bench. https://twitter.com/eatsleeprugby/status/789806377162203136?lang=en The general consensus was that the offence was worthy of a sending off according to the letter of the law. https://twitter.com/patmccarry/status/789805906196369408?lang=en https://twitter.com/benfharries/status/789807813157683200?lang=en https://twitter.com/GegseNagle/status/789810637954252800?lang=en https://twitter.com/minisandmum/status/789809258380558336?lang=en However, not everyone agreed with the decision. Bath winger Matt Banahan argued that Brown twisting his body mid-air made it look worse than it actually was, and therefore it was only deserving of a yellow. https://twitter.com/mattbanahan1/status/789806340864634880 In the latest GAA Hour, we talk to Ken McGrath of Waterford and with Declan Brennan about a new club players' association.
