Paul Dickov expects Enda Stevens to hit the ground running after capturing the Aston Villa defender on loan.
Left back Stevens, 24, has been drafted in as cover for the injured Cedric Evina and will go straight into the squad for tomorrow’s FA Cup tie at Weston-super-Mare.
Stevens, on loan at Northampton Town last month, made 14 appearances on loan for Rovers last season.
“It’s a good fit,” said Dickov.
“Like we said when Sam [Johnstone] came back, he knows the place, the players, the club and myself.
“And like Andy Butler he’s just been out recently and had some games. He’s not playing catch-up fitness wise.
“We’ve seen the benefit of that with Andy, who has came in and hit the ground running. Enda will do the same. We’re delighted to have him back.”
Stevens has signed initially for a month.
He, Johnstone and Butler will all be eligible to play for Doncaster in cup competitions, Dickov said yesterday.
The Scot also revealed he had asked England Under 21 boss Gareth Southgate to leave Johnstone out of his squad for forthcoming friendlies with Portugal and France, so the goalkeeper can play for Rovers next weekend against Sheffield United.
Rovers will definitely be without Butler (ineligible) and South African international Dean Furman against the Blades.
However, Luke McCullough could still feature - despite being named in the Northern Ireland squad.
Dickov, meanwhile, is hopeful Evina’s absence will be limited to four weeks, despite suffering knee medial ligament damage and a small stress fracture.
