Coach Vic Fangio said Friday that the herniated disk in Flacco’s neck requires six weeks of rest and it would have taken another two weeks to get the veteran QB back up to speed.

Flacco’s first year in Denver ends midway through the season with 1,822 yards passing, six touchdown throws and five interceptions.

The notoriously immobile quarterback also was sacked 26 times behind Denver’s porous offensive line, including a career-high eight against Kansas City two weeks ago and three Sunday at Indianapolis, after his neck was so stiff he couldn’t turn his head.
