The Leeds captain’s previous good conduct was also taken into account. He had been charged with a Grade C offence, which carries a two to three-game ban.
His previous record meant that Sinfield could submit an Early Guitly Plea (EGP) and receive the lower end of that punishment tariff.
The EGP also meant that he did not have to appear at tomorrow’s disciplinary hearing.
The outcome did not stop Leeds chairman Gary Hetherington casting aspersions upon the consistency of the RFL disciplinary process, however.
“Unfortunately this is another example of the pattern of inconsistency displayed by the Review Panel of the RFL,” he told his club’s official website.
“I can fully appreciate the growing chorus of discontent throughout the game with the performance of the RFL in these matters.”
