CLEVELAND, Ohio — The Browns will not face Joe Flacco when they take on the Broncos on Sunday in Denver. Broncos head coach Vic Fangio ruled Flacco out for Sunday's game with a neck injury and said they will re-evaluate after their bye week following their game against the Browns.

Brandon Allen will make his first career start in Flacco's place.

Allen is a former sixth-round pick by the Jaguars out of Arkansas in 2016 and is in his third season. He has not thrown a pass in the NFL.

The Broncos didn't rule out bringing rookie Drew Lock off of injured reserve to serve as Allen's backup They could also promote Brett Rypien off their practice squad.

Flacco expressed frustration with the Broncos' coaching staff's late game decision-making following Denver's 15-13 loss to Indianapolis on Sunday.

From ESPN.com's Jeff Legwold:

"'Well, c'mon, I just look at it like we're now a 2-6 football team, and we're like afraid to go for it in a two-minute drill, you know?' said Flacco, who received medical treatment on his neck throughout the game. 'Who cares if you give the ball back with a minute, 40 seconds left? They've obviously got the field goal anyway.'"

Injured reserve could be a possibility for Flacco once he is re-evaluated.
