Tiger Woods, who has worn Nike apparel since first signing with the company in 1996, has parted ways with the sportswear giant, the 15-times major champion said Monday in a social media post.

Woods had been a brand ambassador for Nike since 1996 when, as a 20-year-old, he signed a five-year, $40 million contract upon turning pro in what was the start of one of the most lucrative endorsement deals in sports history.
