(CNN) -- Three-time winner Tiger Woods followed defending champion Ian Poulter out in the first round of the WGC Match Play Championship in Arizona.
Former World No. 1 Woods lost to Denmark's Thomas Bjorn on their first extra hole at the Dove Mountain course and could slip to as low as number eight in the rankings after his error-strewn defeat.
He managed to extend the match with a eight-foot birdie on the 18th, however, the 35-year-old then hit his tee shot from the first playoff hole into a bush on the side of course.
The American took two shots to recover from the mistake to card his fourth bogey of the match and all but hand victory to Bjorn.
Woods has gone over a year without a tournament win after his well-publicized off-course problems and his attempts to remodel his swing.
England's Poulter also lost at the first extra hole to his American opponent Stewart Cink as the 2009 British Open champion made a birdie putt to wrap up an unlikely victory.
Poulter was two up through the turn but Cink made a series of lengthy putts to draw level again at the 17th hole when he made an impressive par-four despite finding two bunkers. CNN
