Leeds Rhinos lose forward to suspension after gruelling clash with St Helens

McDonnell was sent off in the closing stages of normal time for punching, described by the match review panel as 'one on one – contact to the head'.

The Rhinos went on to lose the game in golden point and are now set to be without McDonnell for Saturday's Magic Weekend meeting with Castleford Tigers and next week's game against Wakefield Trinity.

McDonnell, who has scored three tries in 11 games since joining from Wigan Warriors in the off-season, was also fined £250.

Fellow second-rower Zane Tetevano is available after serving a suspension for his recent red card at Wigan but Leeds are facing a selection crisis ahead of the trip to St James' Park.

Aidan Sezer, Harry Newman and Morgan Gannon joined Blake Austin, David Fusitu’a, Sam Lisone, James Bentley and Jack Sinfield on the sidelines after being forced off in the first half against St Helens.

Leeds outside back Nene Macdonald and Saints forward Sione Mata’utia were also charged in the aftermath of a gruelling contest but both players avoided suspension.

Mata’utia was fined £250 for grade A dangerous contact following his yellow card in golden point, while Macdonald escaped punishment for grade A other contrary behaviour.

Elsewhere in round 13, Hull KR prop Jesse Sue and Salford Red Devils front-rower King Vuniyayawa received fines.
