SEAN O’Driscoll will step up his pursuit of another centre half after landing defender Richard Naylor.
Naylor, 34, was officially unveiled as a Doncaster player yesterday after agreeing a short term deal with Rovers - thought to be a three month rolling contract.
It brought to an end a drawn out period of negotiation with the former Leeds United skipper, who will bring a wealth of experience with him to the Keepmoat Stadium.
But his arrival won’t deter O’Driscoll from attempting to further bolster his defensive ranks before the start of the new Championship season.
Centre back Shelton Martis is expected to be out for another three months after undergoing ankle surgery this summer, while Adam Lockwood is unlikely to play again this year following a knee operation.
James O’Connor could also miss most of pre-season with a cartilage problem.
The departures of Dennis Souza, Byron Webster and loan man Matt Kilgallon have also left Doncaster stretched in the centre half department.
O’Driscoll ran the rule over three trialist centre backs at Armthorpe last week, including 19-year-old Algerian Rachid Bouhenna.
He hopes to recruit one more centre half to challenge George Friend and Naylor for a starting berth at Brighton on August 6.
