Scott Harrison is ready to launch a "new chapter" in his career when he faces Liam Walsh at Wembley Arena on Saturday night.

The lightweight showdown will be the third fight of Harrison's comeback, which began with two routine victories in 2012 that ended six years out of the ring due to personal problems and a spell in a Spanish prison.

The 35-year-old Scot denies there is a drive to make amends as he targets becoming world champion for a third time. "I don't feel like I've got to make up for lost time. I see it more as though I'm beginning a new chapter in my career," he said.

"I'm not interested in lost time or what's happened or my age. What's the point of that? You just keep looking forward.

"I feel good, I'm making the weight Okay. I can't wait for the fight. Of course I've still got a world title in me - maybe two!

"Training has gone well and the sparring has been brilliant. I'm glad to have the chance tomorrow and to move on with my career."

Walsh is unbeaten in 13 fights but he has yet to oppose a fighter of Harrison's calibre - even if doubts persist over how much the veteran Glaswegian has left to offer the sport.

"I've seen a bit of Liam. He's undefeated and a switch hitter. He's going to be confident and it will be a decent fight," Harrison said.

Frank Warren, who is promoting tomorrow's 'Rule Britannia' show headlined by Nathan Cleverly's WBO light-heavyweight title defence against Robin Krasniqi, laments Harrison's troubled past.

"Scott is one of the UK's best world champions I've seen in 15 or 20 years. He's probably one of the toughest people you'll ever see in a ring," Warren said.

"He won't want to hear it again, but it's a shame the way it's gone. But there's a chance here for him now and it's an intriguing fight."
