Denver Broncos starting quarterback Joe Flacco is expected to miss around 5-6 weeks with a herniated disc in his neck.

Flacco is currently getting a second opinion:

With Flacco out, quarterback Brandon Allen is expected to make his first career start.

If Flacco does not return until Week 14, Allen will have matchups against the Cleveland Browns, Minnesota Vikings, Buffalo Bills, Los Angeles Chargers, Houston Texans and Kansas City Chiefs.

So far in 2019, Flacco has 1,822 passing yards, six touchdowns and five interceptions with a 65.3% completion percentage.

Flacco's injury is yet another misgiving in the Broncos' already tough 2019 season. Currently at 2-6, the Flacco injury could be a deciding factor in whether the Broncos will be sellers with the trade deadline coming later Tuesday.

Players like Chris Harris Jr., Derek Wolfe and even Von Miller could be dealt as the Broncos prepare for another disappointing season resulting in a high draft pick.

With the injury coming now, the Broncos might even consider sitting Flacco for the rest of the season, especially with very slim odds of making the playoffs this year. Denver could be more suited for April when the draft rolls around and the team has a high pick in the first round.

Denver will have to wait to see Flacco's successor even with his injury, as rookie quarterback Drew Lock was initially placed on injured reserve with a thumb injury. However, Lock is eligible to return to game action against the Browns this week.

It looks uncertain though that Lock will see the field, as the Broncos upgraded Brett Rypien from the practice squad to be Allen's backup.
