Liam Kent has played his last game for Doncaster after agreeing to join Featherstone Rovers on loan.
The second-rower has been playing for the Dons as part of a dual-registration arrangement with Super League Hull FC, and helped them collect a 22-10 Championship win at Barrow on Sunday.
“We could have kept Liam until the end of the season but I don’t think that is in the best interests of the player,” said player-coach Paul Cooke.
“So we have come to an arrangement whereby he returns to Hull until after our game at Featherstone on Sunday and then he will join them on loan until the end of the season.
“It’s a massive blow losing Liam because he has been fantastic for us and he’s become one of the group. He’s enjoyed it here and respects the players and what we are aiming to do.
“He does a lot of work which perhaps goes unnoticed by some people, but not by me.
“It’s sad to see him leave but we obviously understand the reasons behind the decision.”
The Dons will head to Featherstone, which is the match of the day in the Championship, on the back of three successive wins following their success at Craven Park.
“It was a tough game, which we knew it would be up there, and we were pleased to have come away with the three points,” said Cooke.
“It was only 10-6 at half-time but I felt that we should have been further ahead at that stage and to be honest we should have won by more than we did.”
Cooke expects to have the results of prop Mark Castle’s scan this week.
He is not certain whether the club will again have the services of Hull favourite Richard Whiting, a former Featherstone player, on Sunday.
