Rory McIlroy will have no competitive tune-up for the U.S. Open, after it was confirmed he will skip the Memorial Tournament as he continues to recover from a rib injury.
McIlroy pulled out of this week's BMW PGA Championship at Wentworth, the flagship event on the European Tour, due to the issue, which has dogged him for much of the year.
Having been sidelined for several weeks by a rib problem that caused him back pain earlier this year, the world number two reported similar discomfort - albeit not as severe - during the Players Championship last week.
His agent Sean O'Flaherty told Golf Digest: "All focus is on getting back to full health for the U.S. Open."
After confirming his absence from Wentworth, McIlroy reported that he had not suffered a fresh injury, but the Northern Irishman will travel to Erin Hills having not played for a month.
