Our friend Joey Knight of the Tampa Bay Times reported late last night that USF football offensive lineman Grant Polk has been medically disqualified due to multiple concussions within the last calendar year.
Tough news here: @USFFootball junior OL Grant Polk has been medically disqualified after sustaining his second concussion in less than a calendar year, according to his father.

Polk transferred from UVA during fall camp in 2016 and sat out to satisfy the NCAA transfer rule. He appeared in three games as a reserve offensive lineman for starter Eric Mayes.
