This is the best possible news, but, like PuckHead implied, other players have been day-to-day and been out for much longer. Armstrong, for one, said that he'd be back "in a couple days," but is still out of the lineup a week later. Still, the signs seem to be good. I think that JR is done for the preseason and could possibly miss the first few games of the regular season, but as long as that's all it is, then that's better than fortunate. I actually wouldn't mind if he just skips the next two weeks as a precaution, anyways, just to be safe.
