August 14, 2017 -- Cincinnati, Ohio
Despite winning the Western & Southern Open seven times, Roger has withdrawn from the 2017 tournament.
"I am very sorry to pull out of the Western & Southern Open as I always enjoy playing here," he said. "Cincinnati has some of the best fans in the world and I am sorry I will miss them. Unfortunately, I tweaked my back in Montreal and I need to rest this week."
A lucky loser will replace him in the draw and have the benefit of a first round bye.
Roger's withdrawal assures Rafael Nadal will return to No. 1 in the Emirates ATP Rankings when the new rankings are released on Monday, Aug. 21.
