Herbstreit, a junior, is the son of former Ohio State quarterback and current ESPN analyst Kirk Herbstreit, who posted a note on his son’s behalf to social media.

“I have had a bit of a setback these past couple of weeks. Not feeling right. Culminated with tests results this past Friday that forced me into the hospital. I have some of the best cardiologists looking after me, and I am beyond appreciative,” Zak said in his dad’s Twitter post.
