Denver Broncos quarterback Teddy Bridgewater will miss his team's season finale against the Kansas City Chiefs.
The team announced he went on injured reserve.
Head coach Vic Fangio said Monday that Bridgewater's status was up in the air.
"Well, right now Teddy is still in the concussion protocols, so we don’t really have any new information there," he told reporters. "It will be Drew [Lock] going forward."
Bridgewater was carted off the field in the second half of his team's Week 15 game against the Cincinnati Bengals.
The 29-year-old was brought to a hospital and stayed overnight for evaluation before being released the next day.
