Head coach Sean McDermott spoke at his press conference and was reluctant to go into the details. Davis made it clear that money is not worth his physical or mental health and happiness.
It wasn't how the 10-year National Football League veteran imagined his departure, but in a post-game statement, he said the physical toll was what dawned on the field.
Davis' impromptu retirement caught many of his teammates and fans off-guard.
"I never have seen that. But today on the field, reality hit me fast and hard: I shouldn't be out there anymore", the statement read.
He also expressed that he meant no disrespect to his teammates and coaches by abruptly retiring. "They said he's not coming out". It's just that he holds himself to a certain standard and he was underperforming. Mentally, I always expect myself to play at a high level. But, physically, I know today that isn't possible and I had an honest moment with myself.
The cousin of former 49ers tight end Vernon Davis, Vontae Davis visited with the 49ers and Raiders this offseason, but he chose instead to join the Bills after six seasons with the Indianapolis Colts.
