I'm curious to know what he did. Ultimately from video I thought achilles. (happened just as he burst off the snap). But Underhill said not that... So then you have really only one serious foot injury... Liz franc. Plantar facitits I dont think they would term serious (altho u can have surgery to snip it)
All I know is that dude was rounding into form only to have this. Heart goes out to the young man and hope he can fully recover and get back to being a terror for opponents in 2020
