Scott Quigg has left Gallagher’s Gym and will now train at Freddie Roach’s Wild Card gym, it has been confirmed.
His departure from Joe Gallagher's Lancashire-based team was on "amicable terms" according to Matchroom, his promoters.
The former WBA super-bantamweight champion will move to Los Angeles this week to begin work with Hall of Fame trainer Roach.
"After six years of working together, I announce my departure from Joe Gallagher," said Quigg. "We have been a great team and achieved a lot and had some great wins together.
"I have moved up to featherweight with the goal of becoming a two-weight world champion and believe I need a fresh challenge to help me grow.
"Over the last few weeks, I've been in America training and I'm delighted to announce I will be basing myself in Los Angeles at the Wild Card gym working under the guidance of Freddie Roach.
"This is an opportunity that I couldn't pass up and I believe this move and change will take me to another level. I'd like to thank Joe for everything he has done for me; he is a tremendous coach and friend, which we will remain.
"Our first fight together was for the British title and I went on to become world champion under his guidance and for that I will be forever grateful. I wish Joe and all the lads every success in the future."
Quigg rebounded from a broken jaw sustained in last February's world title unification defeat to Carl Frampton, his sole career loss, to begin his featherweight push with a stoppage win against Jose Cayetano.
