Gronk iffy for Week 1?

As fantasy junkies and New England Patriots fans know all too well, there is really only one thing wrong with Rob Gronkowski's game: an inability to stay healthy. And it appears that issue remains for Gronk and his troublesome broken forearm. No, he didn't re-damage it by break dancing or busting out some pro wrestling moves, but his availability for the start of the 2013 campaign already is in doubt, according to the Boston Herald's Rob Borges and Karen Guregian.
