CNN asked UW–Madison’s Julie Stamm to share her expertise on concussions for a report on Miami Dolphins quarterback Tua Tagovailoa’s Sept. 29 head injury — and an investigation that followed that has resulted in updates to the National Football League’s concussion protocol.

Tagovailoa has revealed that he was unconscious after being thrown to the ground, and does not recall what happened to him immediately after he was injured. Despite this, he was allowed to play again four days after his injury.
“Getting carted off – I don’t remember that,” he said. “But I do remember the things that were going on when I was in the ambulance and then when I arrived at the hospital.”
Stamm is a clinical assistant professor in the School of Education’s Department of Kinesiology whose research focuses on concussions and the consequences of repetitive brain trauma in youth. She told CNN it can typically take 10 to 14 days after a concussion for the brain to get back to its baseline condition.
