Ben Hunter, Latu Makaafi, Michael Heaney and Will Hurrell were selected following a poll of the division’s head coaches.
Knights director of rugby Clive Griffiths said: “I’m absolutely delighted for all the lads who have been selected.
“They are truly representative of a fantastic group of players at Knights. I know they will be first to thank their team mates for helping them achieve this honour.
“All have excelled in their respective positions and thoroughly deserve their selection.”
Here’s what the judges said about Knights; representatives:
HOOKER: BEN HUNTER Combative hooker who has been one of the cornerstones of the Knights’ pack. Has kept Fijian World Cup player Vili Veikoso on the sidelines for most of the season. Marc Jones came an honourable second.
FLANKER: LATU MAKAAFI Tough-tackling Tongan international who carries the fight to the opposition week in week out. Has weighed in with 17 tries, the second best return in the league.
SCRUM-HALF: MICHAEL HEANEY His lightening quick service has been one of the key reasons why Doncaster’s back line has fired so well this season. Defends well for a small man and knows when to go himself. Edged out Bristol’s Will Cliff.
CENTRE: WILL HURRELL All hustle and bustle in midfield, Hurrell has consistently given the Knights go-forward in attack with his ability to run the hard yards and pump his legs through the tackle.
