Playing in pain, part III

Peter Jacobsen withdrew after playing 12 holes because of a back injury. He was 2 over at the time.

According to a Champions Tour official, Jacobsen already was scheduled to have back surgery next Wednesday and likely will be out for a month.

Jacobsen has had six operations in the past three years, including knee surgery and a hip replacement. He had laser surgery on his back Feb. 27, was hitting balls two days later and played at last week's Toshiba Classic in Newport Beach.
