In a first for rugby, the second round of this years' 6 Nations saw a player removed from the field for a head injury assessment (HIA) after an alert triggered by a 'smart' mouthgaurd.

In the opening 20 minutes at Murrayfield, Scotland's George Turner was removed from the pitch for a HIA after an alert triggered by his mouthguard alerted medical staff of a significant head acceleration event; brought about by a tackle made on France's Charles Ollivon. Fortunately, the front rower passed his assessment and returned to the field for the remainder of the game.

World Rugby introduced the new technology ahead of this year's tournament as part of their HIA protocols, which sends alerts of high forces to the independent match day doctor; with the recommendations that male players be taken off for HIA for collisions above a force of 70G and 4,000 radians per second squared, with a threshold 55G for female players.

One-Punch Manslaughter – When A Single Blow Kills (Video)

A split-second decision can change lives forever. In one-punch manslaughter cases, a single impulsive blow, perhaps thrown in anger, fear or misguided bravado, leads to a tragic death. These ‘death by a single punch’ incidents are more common in the UK than many realise. Dozens of families every year are left devastated, with one family grieving an unimaginable loss, and another family shocked and fearful as their loved one faces a homicide investigation for an outcome no one intended. It’s a tragic reality, one moment of anger, one fatal assault involving a single blow, and two lives (and families) ruined.

LNG Charterparty Hire Formula: Meaning Of JKM–TTF Pricing Spread

The Commercial Court ruled on a USD 29 million dispute over an LNG carrier charterparty's index-linked pricing formula, determining whether the "JKM-TTF spread" operated bidirectionally or only when JKM exceeded TTF. The decision examines how unprecedented market conditions—where European gas prices surged above Asian prices due to the Ukraine war—tested the contractual formula's application and whether rectification could remedy an alleged drafting oversight.
