As I've posted earlier, it is almost certainly a compound, midshaft fracture of both tibia and fibula.
It may be comminuted, but likely not to a degree that would impair his chance of a good tibial union.
Assuming no complications (infection, compartment syndrome requiring fasciotomy etc), he has a good prognosis.
There is a possibility of ligament damage in the knee and ankle, which would impair his ability to recover quickly.
This is all based on watching the injury happen, and a fairly good understanding of how bones break and heal.
I have no access to his medical records or information other than what has been released by the team.
With this type of injury, you can get a pretty good idea of exactly what happened just from watching it happen.
