Academic non-qualifiers don't practice while sitting out.
Academic ineligibles (which is what this player would become) still practice according to the following.
Q: What happens if one of my players becomes academically ineligible?
A: Couple of things will happen - you'll lose the player for the next semester (he'll still be on the roster and can practice but just won't be eligible to play). If his cumulative GPA is still not above 2.0 at the end of the next semester, he'll be academically ineligible for another semester. In addition, each time you lose a player to academics, your reputation will take a hit. Remember, these kids are here to get an education. This isn't a minor league program for the NBA you know.
Edit...and in the time it took me to dig that up and paste it, I see three others have already chimed in to this regard. Sorry for piling on.
