Former Leeds United and Reading loanee training with the side to get fit.
Darren O'Dea has played down suggestions a deal to sign for Celtic is imminent, insisting he is just taking up the offer to get fit.
O'Dea had been playing in Ukraine with Metalurg Donetsk but earlier this month negotiated a termination of his contract, due to the city becoming a war zone.
SkySports Scotland reported last Friday that O'Dea had returned to former club Celtic to work on his fitness, in order to help get fit and make the next step in his career.
Enquiries from supporters asking the Republic of Ireland international if he could be signed permanently by the club, have clearly reached the player, with O'Dea addressing the situation on Twitter on Monday evening.
A lot @celtic fans asking about my situation. I'm just doing rehab at lennoxtown as I've had an injury. I'll decide my future once I'm fit!— Darren O'Dea (@odea_darren) September 15, 2014
He was keen to play down talk that any deal could be imminent, but did not rule out joining Celtic permanently. It's likely if asked, he would not turn the opportunity down.
