Fant was a capable starter which feels like an upgrade over last week. He still looks like a guy who could flourish with a bit more experience. It's just hard to imagine him getting that experience with Brown on the team. And honestly, if they plan on replacing Ifedi with him, then It should be a permanent move. Fant needs to settle into one position and get playing time. Juggling him between multiple spots will only hurt his development.
It kind of looked like he came down awkwardly on his ankle. I don't think Pete mentioned him in his press conference, and he played the next 3 snaps. So, I would assume it's not a long term concern... but we'll see.
