Harlequins' Australian centre David Howell has been banned for six games and fined £300 by the Rugby Football League for biting an opponent.
An RFL disciplinary panel found the 27-year-old guilty of biting Catalans scrum-half Remy Marginet in Quins' 48-22 defeat in Perpignan on Saturday.
His ban will run into next season, as Quins have four games left this term.
But St Helens' James Roby is OK to face Wigan on Saturday after being fined for a dangerous throw against Castleford.
Roby pleaded guilty to a dangerous throw on Castleford's Kirk Dixon, but will be available to take on arch-rivals Wigan in the Challenge Cup semi-final after he was given a warning and a £500 fine.
The panel said Roby's guilty plea and his exemplary disciplinary record were taken into consideration.
However, Tigers forward John Davies was fined and given a one-match ban for dangerous contact on Roby in the same game and will miss Sunday's second semi-final against Leeds.
Warrington hooker Micky Higham was suspended for two matches for a dangerous tackle on Bradford centre Paul Sykes, and Wakefield prop Liam Higgins was banned for one game for a high tackle on Crusaders forward Jordan James. Higham and Higgins both received £300 fines in addition.
Howell's Quins team-mate Oliver Wilkes was also banned for one game and fined £300 for a late tackle in the Dragons game.
