Tiger Woods' historic partnership with Nike is no more ... the golfing legend just revealed he's split with the Swoosh after 27 years.
The 48-year-old made the announcement on his X page just minutes ago, thanking Phil Knight ... while reminiscing on the "amazing moments and memories" he's had with the athletic apparel giant.
"If I started naming them," he said of his most memorable times with the brand, "I could go on forever."
Woods first inked a deal with Nike back when he was still an amateur golfer .
