Masters champion Dustin Johnson has apologised for withdrawing from this week's Valero Texas Open, just days after making a late entry into the event.
Johnson committed to the tournament at TPC Antonio on Friday, the same day he was eliminated from the WGC-Dell Technologies Match Play in the group stages.
However, the world number one has changed his mind and will work on his game at home ahead of the defence of his Masters title at Augusta National next week.
"After much careful thought over the weekend, I have decided to withdraw from the Texas Valero Open," Johnson said in a statement.
"I now plan to spend the week at home in preparation for next week's Masters.
"I sincerely apologise to the sponsors at Valero and all my friends in San Antonio, as I realise this is disappointing news. Nonetheless, I have no doubt it will be another great week for the Valero Texas Open."
