NFL Player Tua Tagovailoa's Concussion Might Have Been Prevented With Rugby's Stricter Protocols

(MENAFN- The Conversation)

Few moments in sport are more gut-wrenching than a player lying on the field, limp from the impact of a high-speed collision. The crowd's visceral groans speak volumes, as they did during a game between the Miami Dolphins and the Cincinnati Bengals on Sept. 29.

Dolphins quarterback Tua Tagovailoa was stretchered off the field and hospitalized with a concussion.

In the days since his injury, questions have increasingly been raised about whether Tagovailoa should have been playing at all that night, and whether the NFL needs to revise its concussion protocols to prevent an episode like this occurring again.

If Tagovailoa had been playing rugby, the story of his injury would likely be very different. World Rugby, the governing body for one of the most physical contact sports, has a clear set of guidelines on concussions that map out a pathway for players' recovery that diverge markedly from the NFL and most other professional sports.

There are of possible concussion that require immediate removal from a rugby game with no return to the field of play. A further series of assessments, which take at least a week, and a gradual scaling up of activity ensue in order for players to safely resume participation in contact sport.

These measures are due in no small part to rugby's high incidence of concussion ( and ) and the large number of players embroiled in , such as early-onset dementia.

The size of rugby players over the past few decades. Since 1975, the average player's body mass has increased by nearly four times the amount observed in the previous 70 years. That, together with rugby players' sparse protective gear and the avalanche of lawsuits, has encouraged the game's regulatory bodies to take a far more cautious view of head injuries than almost any other sport.

World Rugby's criteria for concussion would undoubtedly have applied to Tagovailoa in a game on Sept. 25 — in other words, four days before he played against the Bengals. of a Dolphins' game against the Buffalo Bills.

After that play, he reached for his head with his hands, struggled to get to his feet and fell after a couple of steps, clear signs of concussion. He seemed to be propped up by his team mates. Yet, less than an hour later, he was cleared to play and returned in the game.

If Tagovailoa had been playing rugby, he would almost certainly have been barred from returning to that game and been kept on the sidelines on Sept. 29.

In the days following the Bills incident, Dolphins officials, including coach Mike McDaniel insisted that Tagovailoa was being evaluated daily and that his .

He was cleared to start against the Bengals on Sept. 29, but hit his head on the ground again following a tackle in the second quarter. His symptoms pointed to indisputable neurological damage, including a potential brainstem injury. He was carried from the field on a stretcher and taken to hospital for evaluation.

mandate that players suspected of concussion undergo an independent review by an unaffiliated neurotrauma consultant.

According to the NFL, the unidentified specialist who assessed Tagovailoa after the first impact into the decision to clear him for further play. The review is being conducted jointly by the NFL and the players' association, with full results expected within a week or two.

Neuroscientist Chris Nowinski of the , a not-for-profit concussion advocacy organization based in Boston, tweeted after the second head injury:“Two concussions in five days can kill someone. This can end careers.”

Tagovailoa was a fifth-round draft pick in 2020, touted as a possible successor to legendary Dolphins quarterback . While he may have an exciting future, it is hard to argue that a third-round game, even with the Dolphins' unbeaten record on the line, was a strong enough reason to put his health at risk. So why was he cleared to play?

Coaches, players and medical providers are constantly under intense pressure to allow an injured teammate back on the field, given the millions of dollars on the line in salaries, TV rights, endorsements and advertising.

A central issue is that most concussion protocols in professional sports, including the NFL, are subject to an element of human interpretation and judgement. Precise . This leaves doctors leaning heavily on their judgement to make quick assessments in the heat of the moment.

In the case of the NFL, the final decision of whether a player should return to the field lies not with the independent specialist, but with the team physician, adding pressure on the doctor to put the team's interests above those of the injured player.

The more conservative approach favoured by professional rugby has strategic and financial consequences that may discourage its adoption by football and other sport authorities. For example, football's means that the removal of important players for concussion assessments at key times in play can have an immediate and dramatic effect on the outcome of the game.

Furthermore, far more money is involved in football than rugby.

The advantage of rugby's approach, however, is that it greatly improves the . Since 2011 the number of concussions reported in professional rugby games has quadrupled, an increase largely attributed to heightened awareness and changes to protocols.

There is little evidence that the incidence of long-term brain damage is different in the two sports, since the medical consequences of concussion take decades to become evident. However, recognition and removal from play are key to preventing further harm. According to an issued by the Concussion in Sport Group in 2017:

The NFL has signalled that Tua Tagovailoa's case to its rules for the evaluation and identification of concussion. Here's hoping the changes come soon enough to help the next player who suffers a serious head injury on the field.
