John Daly withdrew from Zurich after making the cut

John Daly withdrew during the third round of the Zurich Classic on Sunday because of an injury.

Daly wrote on his Twitter page that he had "no choice" to pull out despite finishing 12 holes of the third round at the weather-delayed tournament.

He said the injury stemmed from his piriformis muscle.

"[B]asically my hip dropped an inch on swing & escalated to my back nerve & dropped me to my knees," Daly wrote.

Playing on a sponsor's exemption, Daly made the 36-hole cut Saturday on the number. He was one-over par and 15 shots off the lead when he withdrew.
