A source with knowledge of the situation said bone chips were removed from Everett’s third and fourth vertebrae and he was said to be on a respirator in the intensive care ward Sunday of Millard Fillmore Hospital in Buffalo, N.Y., the Buffalo News reported Monday.
Everett was injured during a collision with Denver’s Domenik Hixon at the start of the game's second half.
Everett’s agent, Brian Overstreet, said the next few days are expected to be critical to the player's recovery.
"We’re very concerned," Bills cornerback Terrence McGee said. "You always see guys get shaken up and you see some kind of movement. With him I was looking the whole time and I never saw him move. It’s real hard to take. Hopefully everything will be all right."
