Justin Rose has pulled out of this week's Honda Classic due to a troublesome shoulder problem.
The US Open champion has played only two events this year after taking a two-month break to have treatment on tendonitis in his right shoulder.
Rose made his first start of 2014 at the Northern Trust Open in California this month, and he made it to the second round of last week's WGC-Accenture Match Play before being ousted by Ernie Els at the second extra hole.
The 33-year-old was scheduled to play at PGA National in Florida this week before heading to Doral for the WGC-Cadillac Championship, where he lifted his first World Golf Championship title in 2012.
But it has now been decided that his shoulder will not stand up to playing four consecutive weeks, although he is expected to tee up at the Blue Monster at Doral.
His manager Andrew Kipper of Excel Sports released a statement explaining that his withdrawal from the Honda was a precaution, and that scheduling four straight weeks of tournament golf was "aggressive".
The statement read: "While continued rehabilitation continues to help the persistent tendinitis in Justin's right shoulder, scheduling four straight weeks of competition was aggressive to start the 2014 season.
"This was a difficult decision given the quality of the event and the great care Honda takes of the players.
"For Justin's long-term success, this is the proper decision and will allow him to resume his intended schedule for the coming months."
Rose first experienced pain in his shoulder last August when he threw a ball to his caddie at The Barclays during the FedExCup play-offs.
He had posted top five finishes in each of his three previous visits to PGA National, where seven of the world's top 10 players will be competing this week.
