Toru Taniguchi has neck injury
Taniguchi was No. 64 in the world ranking, so the change will not affect the brackets.
Stenson, the first alternate at No. 65 in the world, will face top-ranked Lee Westwood in the opening round Wednesday. Stenson won the Match Play Championship in 2007, the first year that it moved to Dove Mountain north of Tucson. That was on a different course.
The bracket will become official Sunday evening. If anyone withdraws after that, the alternate would take that player's spot in the draw.
