ENGLEWOOD, Colo. — Broncos quarterback Joe Flacco, who ripped Denver’s coaches for their play-calling in their last-minute loss at Indianapolis, won’t play next week because of a herniated disk in his neck.

Coach Vic Fangio said backup Brandon Allen will start Sunday when the Broncos (2-6) host the Cleveland Browns (2-5). Fangio said he’ll decide this week between two rookies as the backup.
