It looked like the leg bent below the knee, not at the knee. Reminded me of Theisman.
Reminded me of Sid Vicious' injury. Wonder is Stamkos suffered a puncture wound as well.
I broke my tibia too as a teen, and was in cast for 3 months, then needed a cane for another month. The challenge here is muscle atrophy. I basically had no calf left after 3 months in a cast. I'm guessing they'll find a way to stimulate the muscles while he's in a cast.
