The NCAA has denied Ty Isaac's request for a medical hardship waiver, Michigan head coach Brady Hoke says.

The USC transfer running back is a former five-star recruit who left his former school in Los Angeles to join Michigan earlier this summer.

Isaac went through the process of applying for a medical hardship waiver to be closer to his mother, who lives in Shorewood, Ill., and is recovering from hearing loss surgery. The procedure his mother underwent prohibits her from flying, which in turn made it almost impossible for her to watch her son play in Los Angeles.

After the move to Michigan, Isaac is still running into issues because the NCAA requires all student-athletes seeking a medical hardship waiver to transfer to a Division I school within 100 miles of the family member in question. Ann Arbor is more than 250 miles from Issac's family home in Shorewood.

Michigan, however, isn't letting Isaac go without a fight.

"The waiver got denied initially, and we've appealed it," Hoke confirmed Wednesday. "(We appealed) probably last week, mid-week."
