Nathan Tyson’s contract has rolled onto the summer of 2016 after an appearance clause in his current deal was triggered.
The 32-year-old striker - a leading contender for Rovers’ player of the year award - joined the club on an initial one-year deal last summer.
Tyson has scored ten goals in 40 appearances this season.
The former Nottingham Forest and Derby County frontman has previously talked about his keenness to remain at the Keepmoat after ‘rediscovering his love for football’ at Doncaster, following loan spells at Notts County and this weekend’s opponents Fleetwood Town.
Tyson’s contract situation is one less for Paul Dickov to concern himself over, but the Scot still faces a busy summer of renegotiating.
In terms of the senior members of the squad, Stephen Bywater, Reece Wabara, Rob Jones, Jamie McCombe, Abdul Razak, Dean Furman, Kyle Bennett and Theo Robinson are all out of contract in June.
On-loan Enda Stevens is set to become a free agent with Aston Villa poised to release the left back.
The vast majority of the club’s younger players - bar Marko Marosi, Paul McKay, Jack McKay and Liam Mandeville - are also out of contract this summer.
Boss Paul Dickov said: “We know what we want to do and the players we want to keep.
“Once I’ve sat down with the board and finalised everything, we’ll be making offers.
“I think the players have a rough idea of who I want to keep and who I don’t through the brief conversations I’ve had with them. We want to keep our best players.”
