The former Leeds goalkeeper has signed a short-term contract at Bolton.
The Irishman was released by the Elland Road side at the start of the current campaign, with his replacement Marco Silvestri faring well in the Championship so far.
But Wanderers have now brought Kenny back to the division on a short-term contract.
The news means the 36-year-old could face former club Leeds on January 10th, when Bolton host them for their first league game of 2015.
Kenny's short-term contract may mean he leaves Bolton before then, however, but he could already feature for the Trotters at Wolves this weekend.
The shot stopper was brought to Elland Road in 2012 when Neil Warnock managed the side.
Now, Neil Redfearn is in caretaker charge at Leeds and Bolton was the first side he beat during his brief tenure so far. Upon the Irishman's release, then Leeds boss Dave Hockaday said: "Paddy has been very professional about it, to be fair to him.
"He was not taken away to Italy (on the club's pre-season tour), although he had been ill a couple of days previously. He has conducted himself really well and I genuinely wish him well. I think he is a good keeper, and I think he is a good lad.
"The club will obviously come to a compromise deal with him and I am sure he will go somewhere and do well."
Had Kenny signed with Dougie Freedman's side a little earlier, he could have been facing his former club even sooner.
