Joe Mauer needs surgery, although it's apparently only going to keep him out for three weeks. If Matt LeCroy gets the majority of the at-bats in Mauer's absence, the hit the Twins take shouldn't be gigantic.

We'll see how much this affects Mauer's ability to catch when he returns, however. Knee injuries are not good for any athlete, of course, but for a guy who's supposed to squat down for an hour and a half every night, they're probably especially harmful.
