J.L. Lewis, a two-time winner on the PGA Tour, announced via Twitter that he has cancer.

Lewis was competing at the Champions Tour's Tradition, the year's second major. He was eight-over par through three rounds when he pulled out of the event Saturday.

"JL withdrew from the Regions Tradition this afternoon. We just found out that J.L. has a serious form of bone marrow cancer," his wife put on Lewis' Twitter account.

"The condition is treatable and the [doctor] feels he can get back to health & playing golf in the future. Keep JL in your prayers."

The 51-year-old Lewis won the 1999 John Deere Classic and the 2003 84 Lumber Classic on the PGA Tour. Since joining the Champions Tour two years ago, his best finishes came at the 2010 Tradition and the 2011 SAS Championship. He tied for sixth at both events.

In his first eight tournaments this year, Lewis has a pair of top 20s and they came in his first two starts of the season.
