Defender Joe Wright has agreed a new contract with Rovers until the summer of 2021.
The 23-year-old has played 81 times for the club since arriving from Huddersfield Town in 2016, and was part of the side that won promotion to Sky Bet League One in his debut season.
He said: “I’m really happy to get this deal over the line, I’ve been talking to the club for a while so I’m delighted to get it sorted.
“It shows the faith the gaffer has in me as I’ve been injured for a while, and it fills me with confidence that he’s offered me a deal.
“I’m a Yorkshire lad so this place feels like home to me, I’ve settled in over the past couple of years and made some very good friends here.”
Rovers face Oldham Athletic in the Emirates FA Cup fourth round at the Keepmoat Stadium on January 26. Tickets can be purchased at tickets.clubdoncaster.co.uk, by visiting the Club Doncaster Box Office, or by calling 01302 762576.
