Amir Khan admits he could be in for a long night when he challenges Andreas Kotelnik for the WBA light-welterweight title tomorrow.
The 22-year-old from Bolton is hoping to clinch one portion of the world title at his first attempt when he takes on the Ukrainian champion at the MEN Arena in Manchester.
Kotelnik, 31, has never been knocked down in his 34-fight professional career and has shown his grit on the three occasions he has already boxed in Britain.
Khan, on the other hand, was demolished inside a minute by Colombian Breidis Prescott last September and is prepared to take a more cautious approach when he bids to snatch Kotelnik's title.
“It's going to be a skilful fight, more about technique, and I don't think it's going to finish early,” Khan said.
“It could be a long fight and if there's going to be a stoppage it could happen late in the fight.
“We sparred 12 rounds in LA and we know I've got the fitness in the tank.
“All I've got to do now is the right thing in the fight, not going all out in the first few rounds and instead picking the right shots, pacing myself and hopefully if it goes 12 rounds we know I'm fit and strong for it.”
