According to ESPN.com, looks like Adalius broke his left arm and is done for the season, or at least a significant number of games going forward.  We can't get any good luck at all this year on the injury front, but it seems like that's the case every year.

The sources cited in the story are unnamed and I haven't found any links or stories that are officially confirmed from the Pats, but a few other new sources are also reporting this as well (including the Herald).
