Los Angeles (AFP) - San Francisco 49ers star Anthony Davis announced he was taking a prolonged break from the sport for health reasons on Friday, reigniting debate about concussion in the NFL.
The talented 25-year-old offensive tackle said he planned to take a "year or so" off from the sport to allow his "brain and body" time to heal.
The announcement comes just months after another 49ers star, 24-year-old Chris Borland, walked away from a lucrative multi-million contract citing fears over the long-term impact of head trauma.
