Moa, 25, was found guilty of a dangerous shoulder charge by the RFL Disciplinary Committee, in light of the incident which saw Broncos hooker Julien Rinaldi helped from the field in the 60th minute of Hull’s 22-14 win.
The Tongan told the club’s official website: “To be honest, I couldn’t believe it when I was sent off, but the referee had penalised me a few times in the game for a couple of infringements and maybe he felt he had to stamp his authority on the game.
“There had been no reaction from their players and the London lads were saying they thought I had been unlucky. There was contact with the head and I accept that, but I didn’t think it was a reckless tackle and I was disappointed to pick up a ban.”
Moa added: “I’m trying to move on and put it behind me now. Even though it was an accident, it wasn’t a tackle I was proud of and I know I’ll be on the receiving end of something like that one day.”
