Seyi Olofinjana today booked a longer stay at Hillsborough as Chris Maguire left on loan.
Olofinjana has been on a month-to-month deal and he has now extended his contract to Boxing Day.
Maguire has joined Coventry until January 5.
The Owls have been trying to get certain players out on loan before today’s deadline because they have not been getting games at Hillsborough.
Maguire has not been involved with Dave Jones’ first team and will welcome the chance of some matchplay.
Olofinjana will hope to earn a place in the side at Blackpool tomorrow after being left out for last week’s clash with Huddersfield.
