They were probably already knicked up from HS, then once they got on campus they were medically evaluated & the staff decides to hold them out of Spring practices as a precautionary measure.
The thing is, a lot of times when they tell us it's not a big deal & they're just going to be out for a little while it usually ends up extending longer than expected.
If they're holding all these guys out in Spring I wouldn't be shocked if they missed time in Fall too, NOT SAYING they will, just saying that's how things often happen with injuries on this team. For whatever reason the initially reported small little injuries that shouldn't last long always seem to linger for months & months on end with this team.
It's something I've still yet to understand about the Richt/Diaz regime, the slightest injuries just never go away.
