Former Celtic centre-back Darren O'Dea has joined Blackpool as a free agent.

The Irish defender has agreed a short-term deal with the Championship club.

O'Dea was most recently at Metalurh Donetsk but left the Ukrainian club in August as a result of the conflict in the region.

Meanwhile, Kevin Doyle has returned to Wolves after his loan spell with Crystal Palace was cut short by a groin injury.

The Ireland striker made just three Premier League appearances for the Eagles this season.
