David Haye has revealed his rehabilitation from bicep surgery is "well under way" and the heavyweight promised to keep in shape over Christmas.
The injury-prone 37-year-old withdrew from a proposed rematch with Tony Bellew, scheduled for December 17, last week after tearing his bicep during training.
Haye hopes to instead fight his rival on March 24 or May 5 and, in a bid to prove his fitness, he posted a video on Twitter in which he was flexing his muscles.
"It's been eight days since my operation on my left bicep and the rehabilitation phase is well under way," Haye said.
"All very steady, all very slow, all very boring, all very monotonous but it has to be done this way to get the results that I require.
"I'm going to try and stay under 100 kilos over Christmas, which isn't always that easy but that's my target."
IN OTHER NEWS: Age is just a number to Matt Sen as he aims to make the most out of professional boxing in his thirties.
He made his pro debut 10 days after turning 30 in July and steps through the ropes for his second bout on Friday night (December 1) when he takes on Nottingham’s Russ Henshaw.
He aims to build on a points win over Dmitrij Kalinovskij when he laces on the gloves again at the Venue on Icknield Port Road in Edgbaston, Birmingham on BCB Promotions’ ‘The Rising.’
Coached by Peter Christie and managed by Gary Stern, the Black Country cruiserweight - full name Matthew Sennett - is originally from Heath Town in Wolverhampton but now lives in Oldbury.
Sen first took up the sport at Wolverhampton Boxing Club as a youngster and has fought on the unlicensed circuit as an adult.He’s now looking to make his mark in the pro ranks and build towards a shot at the vacant Midlands title, which hasn’t been contested in nearly five years.
Dilly Singh, Josh Burke and even Antony Woolery - the latter a new addition to the pro game - have all made noises about challenging for the belt. Sen believes boxing’s big men have a longer shelf life and is hoping to carry on fighting until he’s approaching 40.
