Chesterfield Football Club are delighted to announce that midfielder Jay O'Shea has joined the club on a permanent deal.
O'Shea, 24, mutually agreed to terminate his contract with MK Dons and has now penned a contract to keep him at the Proact Stadium until June 2014.
The Irishman has proved a favourite amongst supporters since his arrival, on loan, in November.
Manager Paul Cook expressed his delight at landing O'Shea, who scored two goals in seven appearances during his loan spell.
"Jay did really well for us during his spell on loan and we're delighted to have signed him on a permanent basis. He is a terrific addition to the squad," Cook told the official website.
O'Shea is eligible to play against Northampton Town tomorrow subject to the completion of paperwork.
