A tragic week has passed on the international sports stage, with two athletes dying and another in the hospital after head injuries on the field.

Australian rugby player Nicholas Tooth died Sunday at the age of 25 after a head injury Saturday. He collapsed after a botched tackle attempt and was airlifted to the hospital, where he passed away.

Indian cricket player Ankit Keshri died Monday after losing consciousness during the CK Nayudu national championship Friday. The 20-year-old’s coach, Joydeep Mukherjee, called the knee-to-neck collision with a teammate “one of the worst sights [he had] been witness to on a cricket field.”

And now another 20-year-old cricket player, Rahul Ghosh, is in the hospital after getting hit in the head during a match on Tuesday. At the last report, he is doing well and will be discharged early next week.

It has been a week of sobering reminders of the dangers that head injuries present. We wish Ghosh a speedy return to full health as he continues his promising recovery, and our thoughts and condolences are with Tooth’s and Keshri’s families, friends, and teammates.

*Scientists have no conclusive evidence as to whether or how the reduction of g-forces during impacts reduces the number or degree of concussions and head injuries. GelDefender products provide supplemental padding as well as cooling and comfort benefits when used with helmets and caps. Participants in activities in which head impacts can occur should always use tested and approved helmets for protection. However, no helmet or supplemental padding can protect the user from all serious head or neck injuries that can result from impacts.
