James Husband says the time was right for him to leave Rovers.
The left back joined Middlesbrough for an undisclosed fee yesterday, sparking what is set to be a busy few days of transfer activity for Rovers.
Striker Curtis Main headed in the opposite direction as part of the Husband transfer while trialist Cedric Evina signed a one-year deal.
Husband told the Star he could not turn down the opportunity to sign for Boro and he hopes Rovers fans understand his decision.
“It’s a brilliant move for me personally,” he said. “After four years at Doncaster I think the time is right for me to further my career.
“Playing in the Championship is a massive lure. I feel that is where I belong after playing so many games last season.
“I came and had a look around on Monday and it’s an unbelievable place. The facilities are top class. I couldn’t turn the move down.”
Husband will reunite with fellow former Rovers left back George Friend, who has made a big impression at the Riverside since switching two years ago.
“George rang me as soon as he heard there was interest,” Husband said.
“He offered me some advice and told me how great a place it is to play.
“It’s going to be interesting going after that left back spot with him.”
The 20-year-old – who joined Rovers’ youth set up after leaving Leeds – says he has a massive debt of gratitude for the club where he made 73 senior appearances, beginning with his debut against new club Boro.
He said: “I can’t thank everyone at Rovers enough.
“They picked me up when I left Leeds and developed me into the player I am today.
“It starts with the youth coaches and runs right through to each of the managers I’ve worked under.
“I’ve had a great few years with Doncaster. The League One campaign was incredible and it was great to play in the Championship last season.
“I can’t speak highly enough of Paul Dickov. The club lost Tommy Spurr and he showed a lot of faith in me to not rush out and bring someone else in.
“He gave me that chance in the Championship and hopefully this move shows I produced what he was after.
“He wasn’t going to stand in the way of this move and I’m really appreciative of that.”
The Star understands the deal for Husband amounts to around £500,000, an amount which includes the valuation of striker Main.
The 22-year-old signed a three-year deal yesterday after agreeing to switch from the Riverside.
Full back Evina also penned a one-year deal yesterday.
Deals are expected to be announced for out-of-contract pair James Coppinger and Paul Keegan today while Dickov continues his hunt for a goalkeeper.
