How hurt is Ganz?

How hurt is quarterback Joe Ganz hurt?  At practice on Tuesday, quarterback Joe Ganz took a shot, but according to offensive coordinator Shawn Watson, Ganz is fine even though he sat out practice yesterday for precautionary reasons. 
With Ganz held out of practice, Watson let back up quarterbacks Patrick Witt and Zac Lee split time with the first stringers.  Watson is confident though that Ganz will be up and running by Sunday, when the Huskers go into normal prep work for the Colorado game.
So it doesn’t appear to be much of an issue, at least the Huskers are downplaying the hit.  Even though normal game week preparations don’t start until Sunday, Watson already taking a look at Colorado’s defense and while their record may not show it, he’s impressed with the Buff’s speed.
