Tua Tagovailoa is set to return to NFL action this weekend after recovering from his latest concussion.
Six weeks ago the Miami Dolphins quarterback suffered his third concussion in less than two years – and fourth overall, including his college career.
Many pundits and ex-players called for the 26-year-old from Hawaii to retire. Some even said the NFL should take the decision out of his hands.

During his absence Tagovailoa consulted medical experts across the US. He said that, after two concussions in 2022, he considered retiring following discussions with his wife and family.
On Monday he told reporters that this time “no-one’s [medical] advice affected anything that I thought in terms of returning” and he “had some conversations with my wife but that was it”.

During a game, it is known as a ‘game day checklist’, and players must clear each step to return to the field.
Outside of games, players must clear a five-step ‘return-to-participation protocol’, which Tagovailoa has been following this week.
