O'Driscoll ponders his options.
Sean O'Driscoll has no new injuries to contend with for Doncaster's clash with Cardiff after the gruelling Carling Cup extra-time defeat at Notts County in midweek.
O'Driscoll made five changes from the side which won at Derby last weekend and should revert back to his strongest possible starting XI for the visit of the Bluebirds.
Striker Darren Byfield has stepped up his rehabilitation after overcoming a hernia problem but is not expected to be involved this week, while Jason Price (foot) should return to training next week.
Young striker Lewis Guy will be vying to add to his opening-day winner at Pride Park, with Paul Heffernan also battling to start.
Defender Sean McDaid (dislocated knee) remains stranded on the sidelines.
Bluebirds boss Dave Jones is facing a striker dilemma for the trip to Rovers.
Ross McCormack and Steve Thompson led the line in the opening-day victory over Southampton - the latter netting the opener in a dramatic 2-1 win.
However, Jones opted for a forward partnership of Jay Bothroyd and Paul Parry against Bournemouth in the Carling Cup and watched as both put in impressive performances - Parry netting a brace.
Gavin Rae and Kevin McNaughton should both be fit after suffering knocks against the Cherries but Glenn Loovens' participation is under threat as his City future hangs in the balance.
Otherwise, Jones is expected to name an unchanged line-up with defenders Darren Purse and Miguel Comminges battling for places on the bench and Tony Capaldi (knee) still out.
