Sean Dyche has confirmed that Joey Barton is training with Burnley.
Barton left Burnley to join Rangers in the summer, but is now without a club after having his contract terminated.
Clarets boss Dyche says Barton is training with the club to “get himself fit, not with the first team”.
“Beyond that, anything else is for the future, he’s just getting himself fit,” he added.
Barton would not be eligible to sign for a new club until the January window, meaning there is no rush for either party to commit to a reunion.
Whether he feels up to the pace of the Premier League, having turned down the chance to stay with Burnley in the summer, is an open question and he is sure to have suitors in the Championship.
After enjoying one of the more serene campaigns of his colourful career at Turf Moor, Barton endured a brief but turbulent time in Glasgow.
He arrived with the stated ambition of being the best player in Scotland, but managed just eight appearances, mostly underwhelming, and was suspended after a training ground row that followed a 5-1 defeat by the Old Firm rivals Celtic.
Barton was later handed a one-match suspension for breaching Scottish Football Association rules on gambling, having placed 44 bets on games between 1 July, when his Ibrox deal started, and 15 September. That suspension will carry over whenever he signs for a new club.
