Westwood was clearly struggling through the first two rounds of Bridgestone as he dealt with a ruptured plantaris muscle that has been plaguing him for weeks now. Westwood -- who had a chance to leapfrog to the top spot in the world golf rankings past Tiger with a strong finish at the Bridgestone -- was nearly in last place, at 7-over for the tournament (a shot behind his playing partner Woods).
Westwood had managed to gut out a second-place finish at the British Open despite his physical ailments, but told reporters that "it just seems to be getting worse" and 'there's no strength in it" at this point. Westwood says that he'll require about six weeks of rest to recuperate -- which means he should be healthy just in time for the Ryder Cup.
