Looks like if a player qualify but doesn't meet certain requirements, he can practice but won't be allowed to play. He will have to take what's being called a "academic redshirt". This will no doubt affect several players. This is straight from the NCAA website:
"For immediate access to competition, prospective student-athletes must achieve at least a 2.3 GPA and an increased sliding scale. For example, an SAT score of 1,000 requires a 2.5 high school core-course GPA for competition and a 2.0 high school core-course GPA for aid and practice.
Prospects also must successfully complete 10 of the 16 total required core courses before the start of their senior year in high school. Seven of the 10 courses must be successfully completed in English, math and science."
