Leeds will be without prop Brad Singleton until late April after he pleaded guilty to elbowing Catalans’ Greg Bird.
Singleton admitted the grade E offence, which happened after the ball had been passed, at last night’s disciplinary hearing in Leeds.
The forward was banned for six matches and fined £300 after being placed on report in the early stages of the 46-10 win over the French club.
The incident left Bird needing seven stitches in the back of his head, with Dragons coach Laurent Frayssinous saying he should have been dismissed.
Singleton – who was accompanied to the hearing by Rhinos player welfare manager Kylie Leuluai – stayed on the field but will now miss six crucial Super League matches, starting with Wakefield on Friday night.
He will also miss both Easter fixtures against Hull FC and Widnes, before returning for the fifth round of the Challenge Cup the following weekend.
Hull utility Jansin Turget also pleaded guilty to a grade C charge of striking with the elbow/forearm and was banned for two matches.
He was sin binned for the offence in the second half of his side’s 24-14 win over St Helens.
Salford’s Lama Tasi accepted a one-match suspension for lifting Wakefield’s Anthony England into a dangerous position, having also been shown the yellow card during the match.
But Widnes half-back Danny Craven took an early guilty plea after being the latest player charged with contact with an official against Castleford, and escaped a ban.
Leigh prop Gareth Hock was handed a £300 fine but also avoided a ban for grade A punching in the win over Huddersfield.
Giants prop Sebastine Ikahihifo was able to take an early guilty plea on the same offence for no suspension, which was also the case for St Helens front rower Alex Walmsley.
His use of the knees on Hull’s Carlos Tuimavave after he had score produced a rare eight-point try in the defeat at Hull, but no further action has been taken against the Saints man.
