Rovers can confirm the signing of forward Alfie May.
The 23-year-old has agreed a two-and-a-half year contract at the Keepmoat Stadium, and officially completed his move from Hythe Town on January 1 2017.
Rovers will pay Hythe an undisclosed fee for the player, who chose a move to South Yorkshire despite interest from a number of other EFL clubs.
May spent a week on trial with Rovers earlier in the season and, after being impressed by the players, staff and facilities, said it was an easy decision to accept the contract offer which followed.
He said: “From the minute I met the players, they came out their way to ask where I was from and introducing themselves. It made it so much easier and took a lot of weight off my shoulders.
“It is a big step, but I feel confident I can play in League Two and training every day will only improve me.
“I’ve done really well in non-league with Hythe, I’ve felt they’ve really got the best out of me, but working with Darren Ferguson as manager is different – I reckon he can get goals out of me too."
Rovers manager Darren Ferguson said: "Alfie’s got good potential. There are a lot of things I like about him, mostly his attitude. He’s got an absolute desire to be player and that was the real thing for me. The level he’s been getting goals at is obviously nowhere near what he is coming into but he is a natural goal scorer.
“He had a week with us in November which gave us a chance to look at him and him a chance to look at us. Hythe have been excellent in terms of managing his situation, and his manager has too, in terms of letting us do that."
Hythe Town boss Clive Cook added: “Alfie now has the opportunity to realise his dream to be a professional footballer and I know he will take it with both hands. He is a smashing lad, easy to manage, easy to get on with and thoroughly deserves to go into full time football. That’s what he wanted and that’s what he has got through hard work, talent, dedication and honesty.
“Alfie came to Hythe Town 16 months ago after I became manager and the first thing that came to mind was what an incredible talent he has. He made 67 appearances for us scoring 49 goals, a fantastic return at any level of football. I would like to thank Doncaster for giving Alfie the opportunity to realise his ambition."
