Player coach Paul Cooke has signed a new one-year contract extension at the Dons - amid interest from other clubs.
Cooke replaced Tony Miller at the end of last season and has guided the club to third place in the Championship.
His new deal ties him to the club until the end of the 2015 season.
General manager Carl Hall has revealed that rival clubs were casting admiring glances towards the former Super League star.
Hall said: “We have had a lot of interest from other teams about Paul Cooke, but he wants to stay here.
“He is doing a fantastic job and we are very grateful that he has agreed to stay here because he is vital for this club.
“We have started with the top man and now we will start working our way through the team.”
On his new deal, Cooke said: “I am delighted to have sorted the contract out nice and early, it gives me and my family a lot of stability.
“It wasn’t a difficult decision to make at all, it was all done this week and I am really pleased to be staying.
“I have really enjoyed my time at Doncaster and I am looking forward to building on what we have started this year.
“I would like to thank Carl Hall and Gavin Baldwin, they have been a real pleasure to work with and have made my job really easy.
“The players also deserve great credit, we wouldn’t be successful without the team.
“I look forward to continuing my work with them all both for the remainder of this season and next year.”
