In this week’s Dolphins Q&A, we address if Tua needs dial back his competitive nature since that’s what led to his most recent concussion when he ran head-first into a Bills safety.

Tua Tagovailoa is back in the fold for the Miami Dolphins. The club is designating him to return to practice this week and, if all goes according to plan, will start in Week 8 when the team takes on the Arizona Cardinals on Sunday.

Tagovailoa is a high-profile quarterback who has now sustained three diagnosed concussions over the span of two years, plus another head injury that prompted the NFL to change its concussion policy. So, naturally, Tagovailoa's health and playing future have been among the most heavily scrutinized stories in the NFL this season.
