Hansen’s caddie injured; Sergio’s backup will take his place

This just in from Paul Mahoney in Louisville: Soren Hansen’s Scottish caddie, John Graham, has had to withdraw from the singles with a back injury. He will be replaced by Billy Foster, Sergio Garcia’s "other" European caddie, who is in Valhalla as part of Nick Faldo’s support team.
