Mizzou has already released a statement about this. Mitchell will not be able to enroll at Mizzou for this semester. The deadline was August 30. Cheno is right that it's not an NCAA issue, though. It varies from school to school (see: Markieff and Marcus Morris enrolling more than two weeks after classes began in 2008).
Just another example where KU outsmarts Mizzou.
Cheno, I think you're wrong on some of the academic fraud details, though. The kansas assistants the NCAA found guilty of providing test answers to recruits weren't helping with the ACT or SAT. They were correspondence courses juco players needed to graduate. That is what you're talking about, right?
Nope talking about Mizzou hiring a guy to physically go take the ACT/SAT tests for Mizzou players. Outrageous.
