According to the PGA Tour's Twitter, the Swede has a foot injury.
44-year-old Stenson started the competition with 69 strokes, two under par, before he had to throw in the towel on the second day of the competition.
He had then played nine bad holes - which ended with seven bogeys and a double bogey.
Henrik Stenson has played sparingly during the corona pandemic and has not been very successful once he has competed.
At best, he has been 21st and in both the major competitions, the PGA Championship and the US Open, he missed the cut.
