The actually weekly designations are only assigned on Fridays. So whatever source is listed him as questionable is doing so on their own and it's not official. We have been discussing similar designations all season, stemming mostly from listings on CBS, Yahoo, MFL, etc. when no injury report was even out yet.
That being said, it has not come out yet when the injury occured and how sever it is. The range is anywhere from hairline fracture (and perhaps a wrap or soft cast with little to no missed time) to a major fracture (and thus potentially season ending).
Given that BB said yesterday the team has no plans to put any of their injured players on injured reserve, I'm guessing it's not a season ending injury.
