Listening to XM Radio's Fantasy Focus with Jeff Erickson, the guest was Will Carroll of Baseball Prospectus, and he reports that Albert Pujol's rib injury is worse than reported so far.
He said it could be felt with the fingers and was still spreading -akin to a bruise spreading.
I'm no doctor, nor do I play one on XM Radio's Fantasy Focus with Jeff Erickson, but that does not sound promising for a return in 15 days.
