VSU quarterback Russ Callaway suffered a knee injury in the next to last place of Saturday's scrimmage.
Blazer team physician Kurt Jacobson confirmed Tuesday Callaway suffered a torn ACL in his right knee.
An MRI later this week will determine the extent of the tear but Callaway is expected to be out anywhere from six to 12 months.
That means he will almost surely will not be ready to play when the Blazers open the season in late August.
