"Football players could be suspended for up to four games, starting in 2012, if they fail to earn at least nine credit hours in the fall semester -- or eight on a quarterly system.
The NCAA will force football players to take more classes in the fall session. It wants to limit the practice of football players taking fewer hours during the season and then loading up on extra classes in the spring and summer to retain their eligibility.
Players who fail to meet the minimum requirements can reduce the suspension to two games if they earn 27 hours in a school year on a semester system or 40 on a quarterly system. But players will only be able to get the reduction once during their college career"
