Vinny update: Vinny is jacked up. The first MRI read indicated torn PCL,LCL, MCL, and ACL, each either partial or full. Additionally, there's a bone chip floating around, and a lot of fluids where they shouldn't be. He's going to a recommended out-of-network specialist tomorrow for another opinion. His father and brother will be here for a while to help take care of him.
Moral of the story: do not fall out of the raft.
