Bryson DeChambeau has withdrawn from this week's Charles Schwab Challenge in Texas with a lingering wrist injury.
The 28-year-old has slipped down to number 22 in the world rankings after an injury-plagued first half to the year.
He has not played since missing the cut at the Masters in mid-April and undergoing surgery on his wrist a few days later.
A return to action at last week's US PGA Championship looked likely, only for him to pull out of the second major of 2022 after taking part in a practice round on the eve of the tournament.
DeChambeau's comeback has now been delayed further as he still does not feel ready to compete to the best of his abilities.
"I'm definitely close but don't have the endurance for four full days yet. Getting there. Taking a bit of time to make sure it's fully healed," he wrote in a text to Golfweek.
DeChambeau previously missed around two months earlier in the season through hip and wrist injuries and has missed the cut in three of his past four starts this year.
