Mouthguards that light up to indicate that a player has sustained a significant head impact are to be used at the Women’s Rugby World Cup, officials announced on Monday.
Mouthguards would flash red if the impact is severe enough to potentially cause a concussion. The referee would stop play and the player would leave the field for a head injury assessment, officials said.
The aim is to introduce the system into all top-flight rugby.

World Rugby chief medical officer Eanna Falvey, a doctor, said that every player at the Women’s World Cup, which is to start on Friday next week, would wear the mouthguards, apart from two who wear braces.
In the men’s game about 85 percent of players wear so-called “smart mouthguards,” which are not compulsory.
The mouthguards measure how much a player’s head moves and rotates in a collision. When it registers an acceleration above a set limit, it flashes.
World Rugby data indicate that while concussion rates are similar in women’s and men’s rugby, “head acceleration” events are significantly less likely for female players.
World Rugby brought in the “instrumented mouthguard” at the women’s international tournament in 2023 before introducing it globally the following year.
Scotland hooker George Turner was the first elite male player to be taken off for a head injury assessment after his gumshield detected a potentially worrying head impact in a match against France in last year’s Six Nations.
Lindsay Starling, World Rugby’s science and medical manager, speaking alongside Falvey at a Twickenham news conference on Monday, said that the aim was to help players rather than merely accumulate information.
“The data set that has grown over the last year is huge,” Starling said. “So now it’s actually making sure that it doesn’t just become a data collection exercise, but we actually understand what that data means and then start putting things in place for players such that they are actually benefiting from the data that’s being collected.”
Mouthguards could help identify foul play, she said, but added: “What everybody needs to understand that, in the same way, a player can get concussed from a pretty small head impact, foul play [can take place] without registering anything substantial.”
The LED mouthguards are to be implemented in top-flight rugby next season, British media reported.

NO HARD FEELINGS: Taiwan’s Lin Hsiang-ti and Indonesia’s Dhinda Amartya Pratiwi embraced after fighting to a tense and rare 30-29 final game in their Uber Cup match The Taiwanese men’s team on Wednesday fought back from the brink of elimination to defeat Denmark in Group C and advance to the quarter-finals of the Thomas Cup, while the women’s team were to face South Korea after press time last night in the Uber Cup quarter-finals in Horsens, Denmark. In the first match, Taiwan’s top shuttler Chou Tien-chen faced a familiar opponent in world No. 3 Anders Antonsen. It was their 16th head-to-head matchup, with the Dane taking his fourth victory in a row against former world No. 2 Chou, winning 21-14, 13-21, 21-15 in 1 hour, 22 minutes. The
Marta Kostyuk’s maiden WTA 1000 title in Madrid came on Saturday thanks to her power, poise and a pair of unexpected lucky shorts. The world No. 23 beat eighth-ranked Mirra Andreeva 6-3, 7-5 in under 90 minutes to secure the most prestigious trophy of her career, her third professional singles title and second in less than a month after Rouen. Yet as the 23-year-old Ukrainian posed for photographs at the Caja Magica, it was not just the silverware that caught the eye. Held alongside her team and her two dogs, Kostyuk showed off a piece of black men’s underwear, prompting
Throwing more than US$5 billion at a divisive new tour and walking away after five seasons does not look like good business, but LIV Golf was not all bad news for Saudi Arabia. Oil-funded LIV, which poached top stars and sent golf’s establishment into a tailspin, helped push the conservative kingdom into global view — one of its key aims, experts said. The exit, confirmed on Thursday after weeks of speculation, does not signal a flight of Saudi money from sport, even after the Middle East war that sparked Iranian attacks around the Gulf, they said. “Saudi Arabia is not
Anastasia Potapova on Wednesday turned tennis heartbreak into history by becoming the first lucky loser to reach a WTA 1000 semi-final with her thrilling 6-1, 6-7 (4/7), 6-3 victory over Karolina Pliskova at the Madrid Open, as Taiwan’s Hsieh Su-wei exited in the women’s doubles quarter-finals. The Russian-born Austrian, who lost in qualifying last week, has capitalized on her unexpected main draw entry and stunned former world No. 1 Pliskova in a roller-coaster clash despite squandering three match points. Potapova’s run has included impressive victories over former French Open champion Jelena Ostapenko and world No. 2 Elena Rybakina. Asked if she had thought
