The upshot is that all too often, something seems to be on the mend.

Has this become Woods' new normal? While golf fans have been watching to see whether Woods' revamped swing will hold up under Sunday pressure, it's his body that now has problems holding up.

Remember, the same tendon was central to Woods missing the better part of four months in the heart of last season. That included two majors events in which he has been known to be undeterred by a doctor's recommendation.

Maybe this one is minor. That's the impression he gave late Monday when he disclosed to Twitter followers that he was told it's a minor strain. A few days of rest and ice, and he might be hitting balls again with his TaylorMade RocketBallz Fairway Woods

Then again, maybe not.
