I had the same injury compound tib/fib break in high school football. It took them about 40 mintues to get me off the field trying to get me into a position where it didnt look like i had two knees. Granted it was 20 years ago and I had to go to 2 different hospitals before I ended up a UofM where they were able to do anything about it. The first two said they just didn't have the capabilities to treat that severe of an injury.
I was in traction for around 20 days and then a wheel chair for 3 more weeks. Before a solid 6 months on crutches, the rod and screws made it all stable but it was a solid year before I could do any sort of impact running. I got the screws out about 4 years after as they were giving me some trouble. So it fucking sucks, and suck for Zinter.
Assuming he got WAY better and quicker care than I did, and the advances of medicine since it happened to me, I would say he is probably going to redshirt his first year in the NFL. With the hardware leg should be able to hold up after that. He is a much better athlete than I and is going to have unlimited resources for rehab so maybe he is back on his feet in time for the season next year. But he is going through some shit for sure.
Someone is going to get a hell of a player late in the draft due to his slide.
Also Go fucking Blue. I thought Michigan was going to beat the breaks off Ohio State again. I did not feel good about giving them the ball back when a touchdown would lose it. Hell of a game.
