Brinson is applying for an NCAA hardship waiver that would grant him immediate eligibility to play closer to home because one of his family members has suffered a severe illness.
Brinson redshirted his first season with the Hawkeyes and played in limited time last year after suffering a foot injury that hampered him most of the year. He had just one carry for 7 yards.
If Brinson can play immediately, it would helps the Knights, who are without starting running back Brynn Harvey for at least the nonconference season. Harvey suffered an undisclosed knee injury during spring ball.
