Rory McIlroy broke his silence about his devastating U.S. Open loss on Monday, saying he would take a few weeks away from the game to "process everything."

The Northern Irishman was in position to end a decadelong hunt for his fifth major on Sunday but threw it away with three bogeys in his final four holes, including two where he missed putts inside of four feet, and lost to Bryson DeChambeau by one stroke.

"Yesterday was a tough day, probably the toughest I've had in my 17 years as a professional golfer," he wrote in a social media post.
