Former Bulls coach Richard O'Kelly could be moving to Bramall Lane with managerial partner Sean O'Driscoll.
O'Driscoll has been given permission by Doncaster to speak to Sheff Utd over their vacant managerial role. Donny chief John Ryan expects O'Driscoll to stay, but is reported to be asking £500,000 for the former Bournemouth man if he chooses to go.
Doncaster are just four points short of the Championship play-offs after steady improvement under O'Driscoll and O'Kelly. The pair united when O'Kelly left Edgar Street for Dean Court in 2004, moving on to the new Keepmoat Stadium in 2006 and winning promotion 18 months later. Over the last two seasons they have achieved comfortable mid-table positions with the second lowest attendances in the division.
