Michigan State’s Kyle Ahrens was injured jumping for a rebound in last week’s March Madness game against Texas Tech. He collided with a player mid jump and landed awkwardly on his ankle. Trainers and medical staff placed his ankle in a splint. He exited the game on a stretcher.

Ahrens was taken for preliminary X-rays that showed no fracture. This is most likely an ankle sprain. Any break, crack or chip in the ankle bone is considered a fractured ankle. A sprained ankle involves a tear or disruption of the ligaments. Grade I sprains occur when a few fibers are torn. Grade II sprains have more structural damage, but retain stability of the ankle. Grade III sprains are a complete tear of the ligament. The severity of sprain can be diagnosed upon an exam evaluating tenderness, swelling, bruising and stability.

Ahrens returned to the bench to watch the final minutes of the game. He is currently in a boot and on crutches.
