His manager, Paul Hennessy of Showsport International, on Monday confirmed the fight to MMAWeekly.com.
"Che has signed a promotional agreement with Zuffa and a bout agreement to face Chris Cope on UFC 138."
Mills (13-4) had been expected to face Joey Villasenor at BAMMA 7 on September 10th, and there is still a fair amount of confusion about whether he is in fact contracted to the English promotion. He is currently on a four-fight winning streak, with his last win coming over Marcio Cesar at BAMMA 6 in May. Cope won his TUF 13 finale fight via unanimous decision over Chuck O'Neil to improve to 5-1 overall, and will be looking to continue his two-fight winning streak with a win over Mills."Che has signed a promotional agreement with Zuffa and a bout agreement to face Chris Cope on UFC 138."
