An investigation into the circumstances surrounding Tua Tagovailoa's concussion this week is expected to last "another week or two," according to ESPN's Adam Schefter.
The results are expected to be announced "almost immediately after."
The Miami Dolphins quarterback appeared to display concussion symptoms in his team's Week 3 win over the Buffalo Bills, but he was allowed to return to the game. Four days later, Tagovailoa suffered another big hit in a matchup against the Cincinnati Bengals and was carted off the field.
The NFL and NFL Players' Association are conducting a joint investigation, which will include an interview with Tagovailoa.
