I'm not suggesting that was the reason for the stoppage.
Why was the play stopped though, even in super slo mo there wasn't anything in it
JT was hit several times later and in more dangerous positions, and there was nothing said
One ref thought it was high, once play was stopped they realised it was nothing and went back for the play the ball. Anyway it was a bad moment for the refs made worse by the fact they completely missed that shoulder charge. Nothing suspect though, just the usual shitty refereeing.
