British boxing promoter Frank Warren said Ricky Hatton's break from boxing played a big role in his welterweight defeat against Vyacheslav Senchenko at the MEN Arena on Saturday night.
Hatton came out of retirement for his first fight in more than three years against the Ukrainian but was counted out after a body shot in the ninth round.
Warren said: "You can have time out if you keep yourself well but his lifestyle didn’t help. The shot that actually stopped him, the body shot, was the sort of shot that shows your lifestyle does catch up with you.
"That’s a vulnerable part of the body, maybe a few years ago he would have taken that shot to the body."
The Hitman struggled with alcohol and drug problems while away from the ring and announced his retirement for a second time following the fight.
Having given up alcohol to prepare for the fight Warren said he now hoped the 34-year-old would remain involved with boxing outside the ring.
"Now let’s hope he can keep his focus on still continuing to be involved in boxing but doing it for a couple of fighters he manages and promotes who did do well last night. He was never ever going to get back those glory days."
