Rovers striker Alfie May has signed a new deal with the club until the summer of 2020.
The 25-year-old has scored 11 goals this season, which is already his best tally since signing for the club in 2017.
He said: “It means a lot to me as this is my first professional club, it’s good to get the deal done and now I can kick on.
“I’ve worked a lot on my game during my time at the club, but after conversations with the manager I know I can still improve a lot more.
“I’m still learning the trade really, it’s been a really good two years and the goals are starting to come more regularly now.”
You can see Alfie back in action at the Keepmoat Stadium against Burton Albion on Saturday 19 January, with tickets available from tickets.clubdoncaster.co.uk.
