Craig Bellamy is poised to make his Cardiff debut against Doncaster after the club confirmed his registration to play.
The Bluebirds are anticipating a bumper home crowd for the Championship clash, following Bellamy's arrival at his hometown club on a season-long loan from Manchester City earlier this week.
Bellamy's availability could see boss Dave Jones switch to a 4-3-3 formation, with the Wales international joining Michael Chopra and Jay Bothroyd in a three-pronged attack.
Stephen McPhail has returned to light training this week following cartilage surgery.
The clash with Rovers comes too soon for the former Leeds player but fellow midfielder Jason Koumas could return to claim a place on the bench.
Teenager Aaron Wildig has returned to training but will miss out with a knee problem.
Doncaster defender Wayne Thomas could make his full debut.
Thomas, who signed a one-year deal last week following his release from Southampton, stepped off the substitutes' bench to replace Shelton Martis against Bristol City on Saturday.
Manager Sean O'Driscoll could be without James Hayter again. The striker missed out last weekend due to a hamstring strain, so Dean Shiels is likely to continue alongside Billy Sharp up front.
James Coppinger, a second-half substitute last weekend, is pushing for a return to the starting line-up after shaking off a leg injury while striker Steve Brooker, fit again after his ankle injury nightmare, is hoping to play a bigger part following two previous cameo appearances.
Midfielder John Oster and defender James Chambers remain sidelined with their respective knee injuries.
