Sport: Boxing on Dave
As part of Dave's growing catalogue of live sport, this week David Haye's new stable of fighters gets its first outing on the channel.
Former Olympian Joe Joyce headlines the fight night as he goes up against South London rival Ian Lewison.
Speaking to the RTS earlier this year, David Haye praised Joyce, who has recently been Anthony Joshua’s sparring partner. “If you ask [Joshua] what he thinks of Joe Joyce, he will say, ‘you can’t hurt him. He’s 6’6”, solid grip at 18st and he’s a force to be reckoned with. [Plus] he’s a very nice lad as well. You can’t help but want this guy to succeed.”
