Two British pairings will kick-off the WGC Accenture Match Play Championship in California on 28 February.
Darren Clarke faces Justin Rose
Colin Montgomerie lines up against fellow Scot Paul Lawrie, while Northern Ireland's Darren Clarke plays England's Justin Rose.
The tournament splits the world's 64 best golfers into four groups of 16, each headed by one of the top four tournament seeds.
That sets up the possibility of a mouth-watering clash between Ernie Els and Tiger Woods to determine who walks away with the $1m first prize.
Montgomerie vowed never to set foot on an American golf course again after being heckled in the event last year.
But the Scot has had a change of heart and will begin his campaign against his former Ryder Cup team-mate.
Clarke, meanwhile, will be hoping for better luck on the course after being disqualified at the Buick Invitational.
Clarke won the World Match Play three years ago when he sensationally beat Woods and will be hoping for more of the same at La Costa.
His opponent Rose, who shared fourth place in the Johnnie Walker classic, is making his debut at the event.
Japan's Toru Taniguchi, ranked 55th in the world, is not expected to take up his place.
Taniguchi has not played since discovering a non-cancerous tumour in his leg.
Robert Karlsson is likely to step in for Taniguchi, and would meet Woods in the first round.
The event draw takes place next Monday based on the world standings, and there are some interesting pairings in prospect as things stand.
Ninth seed Padraig Harrington stands to open against German Alex Cejka, Paul Casey may take on fifth seed Retief Goosen and Nick Faldo could meet Jim Furyk.
