Jack Nicklaus will compete with Tiger Woods and Phil Mickelson in a Skins Game on the eve of this week's Memorial tournament, organizers said Tuesday. The 10-man competition, which raises money for charity, will also feature former world No. 1 Ernie Els of South Africa, Britain's Rory McIlroy and Americans Steve Stricker, Zach Johnson, Jim Furyk, Kenny Perry and Sean O'Hair. World No. 1 Woods, the defending champion this week who will be seeking a fifth Memorial title, won last year's Skins Game with a dramatic chip-in. Nicklaus will tee off in the first ‘skins' group Wednesday with Masters champion Mickelson, O'Hair, Perry and Els. Woods will play in the second group alongside McIlroy, Stricker, Johnson and 2002 Memorial champion Furyk.
