Former Masters champion Charl Schwartzel is taking a month off after the U.S. Open because of a nagging rib injury.

Schwartzel has withdrawn from the Travelers Championships next week in Hartford, Conn., and the South African does not plan to play again until the British Open at Royal Lytham & St. Annes.

He has decided to play the final round of the U.S. Open on Sunday at The Olympic Club. Schwartzel says he has experienced discomfort all week, and doctors told him he should take three weeks to rest. He says if he doesn't take a break, it could be months before it goes away.

Schwartzel still managed a 7-over 217 through three rounds at Olympic.
