Canada midfielder Ismaïl Koné suffered a serious left-leg injury during the match against Qatar and had to leave the field on a stretcher surrounded by FIFA medical staff. The incident drew attention not only because of the injury itself, but also because of a small green device placed in his mouth during treatment on the pitch.
The device was identified as Penthrox, also known by its full name, methoxyflurane. It is a fast-acting painkiller used by medical teams in trauma and severe injury cases. The medicine is inhaled through a small portable green device, nicknamed the “Green Whistle,” and is designed to work quickly while the patient is receiving initial care and being taken to hospital.
According to the report, Penthrox is widely used in emergencies when rapid pain relief is needed before tests, transport, or procedures. It is easy to carry, does not require complicated equipment, and provides a relatively quick effect. The article was published on June 19, 2026, at 16:25.
