Mickelson's wife diagnosed with breast cancer

Phil Mickelson's wife, Amy, has been diagnosed with breast cancer, and the three-time major champion says he will suspend his PGA Tour schedule indefinitely.

Mickelson's management company says Amy Mickelson will begin treatment with major surgery as early as the next two weeks.

They were married in 1996 and have three children.

Mickelson was to play the Byron Nelson Championship this week, and defend his title next week at Colonial.
