Concussion, the stuff rugby fans and players of yesteryear used as a measure of physical toughness, is under the spotlight in an agreement between two of Northland's heavy-hitters.
The region's rugby league and rugby union bosses shook hands last week on a reciprocal agreement to address the issue of players crossing between the codes after suffering concussion.
"It's player welfare that's the main concern," Northland Rugby Union chief executive Jeremy Parkinson says.
The agreement, a first for New Zealand, is set to discourage the "heroic" tag surrounding concussion victims playing on.
Many league fans will be able to cast their memory back to the 1991 match between Australia and New Zealand in which Kiwi Dean Lonergan spent several minutes on the pitch, at Melbourne's Olympic Park, convulsing after a heavy knock to the head.
