Warrington winger Tom Lineham has been given a two-match ban for striking.
Lineham was sin-binned in the 55th minute of Warrington's Betfred Super League defeat at Leigh last Thursday for using his elbow on Ryan Hampshire.
The Rugby Football League's match review panel charged Lineham with a grade C offence, which he sought to have downgraded when he appeared in front of a disciplinary panel in Leeds.
Lineham, who declined the opportunity to submit an early-guilty plea, lost his plea and was also fined £300.
His ban rules him out of Friday's derby at St Helens and a reunion with his old Hull team-mates a week later.
Leigh back-row forward Glenn Stewart was suspended for two matches after admitting a grade C high tackle in the same match on Warrington stand-off Kevin Brown.
The former Australia international was sent to the sin-bin six minutes into the second half for the challenge.
Wakefield captain Danny Kirmond was fined £300 but avoided a ban after being found guilty of a grade A high tackle on Leeds scrum-half Rob Burrow in his side's defeat at Leeds, freeing him to face Leigh on Thursday.
