McColl signs for Leeds, Roberts returns to Bristol
Doncaster have confirmed Stevie McColl and Tristan Roberts are set to leave the club at the end of the season.
The Knights have already seen Michael Cusack announce he will be joining Glasgow in the summer - with McColl and Roberts also revealing their departures.
Highly-rated full-back McColl has agreed a deal with Leeds Carnegie, while prolific scorer Roberts will return to Bristol.
Knights director of rugby Brett Davey said: "Stevie McColl has been an example of professionalism in all he has done through this period and I can't thank him enough for that.
"His attitude and behaviour, on and off the pitch in this time of contract talks has been nothing short of perfect professionalism and could be held up as a lesson on how to conduct yourself in this sport.
"I spotted something in Stevie when I first saw him and he has developed, by putting in a lot of hard work himself, into possibly the best full-back in this league and I'm proud to have been a part of his development."
