Baseball Prospectus | Under The Knife: Blue Moon Rising:
"Soft tissue heals better because of a number of factors and is much easier to take the weight off over bone, which can be stressed by more than just simple weight bearing. With the progress Mauer has already made, it's possible that he could be back by the weekend, though the Twins are definitely going to err on the side of caution. There's been some talk of using Mauer at DH for a couple days, giving him some additional healing time without the rigors of catching and giving the team a couple more looks at Wilson Ramos. Ramos' play is said to have the Twins brass excited enough to actually discuss moving Mauer from behind the plate on a full-time basis."
If this were reported in NY papers, I'd be convinced the reporter was doing the bidding of ownership to pump up a player's trade value.
