Golf greats Tiger Woods and Phil Mickelson will go head-to-head in a winner-takes-all $9m (£7m) exhibition match in Las Vegas.
The Americans, who have 19 major championship titles between them, will face off in the 18-hole event at Shadow Creek Golf Course on 23 or 24 November.
The contest, which coincides with Thanksgiving weekend in the US, will be screened on pay-per-view.
Woods confirmed “The Match” on social media, saying: “It’s on”.
Mickelson, who has attracted almost 100,000 followers in less than 24 hours on Twitter, replied to Woods, saying: “I bet you think this is the easiest $9M you will ever make.”
At present the US Open delivers the largest winning pay cheque of the four major championships at about $2.16m (£1.68m), though the winner of the FedExCup – awarded for an accumulation of points on the US PGA Tour – can expect to earn a bonus of $10m (£7.8m).
The possibility of a duel between the former Ryder Cup team-mates has been mooted repeatedly down the years.
Woods, a 14-time major winner, has won over £88m prize money on the PGA Tour in comparison to Mickelson’s £68m.
“It’s an opportunity for us to bring golf to the masses in prime time during a period where we don’t have much going on in the world of golf,” Mickelson told ESPN.
“It’s a way to show a side you don’t normally see by having us mic’d up to hear some of the interaction between us.”
Despite the good-natured approach, there is no chance of the duo sharing the purse, with Mickelson saying that the event had to be winner-takes-all.
“If you [don’t] do that, it undermines it,” Mickelson said. “The whole point is the winner-take-all thing. That’s the exciting part about it.”
