It's not really a freak injury, his biggest problem and why he's getting hurt is because he doesn't know how to land. They need to work on his leg strength, his core and focus on how he comes down after he jumps. He often lands straight legged and on his heels which is basically the worst possible way to come down.
But, whoever let him play that game on the 27th should lose their job. They've known he's had a torn meniscus since the 20th, yet they let him play a game against Houston on the 27th, and he's practiced the entire month since then.
