The Baltimore Ravens have been without the services of starting quarterback Joe Flacco for much of the offseason due to a shoulder injury that he suffered before the start of training camp.

Since then, the notion has been that Flacco would be ready to go for the season opener against the Cincinnati Bengals on Sept. 10. Head coach John Harbaugh once again reiterated that point on Saturday as he stated that the 32-year-old would be full tilt by Week 1, according to Jamison Hensley of ESPN.

“He will be back for the Bengals game, I promise you that,” Harbaugh said after Saturday's 13-9 preseason victory over the Buffalo Bills.

There has been no indication otherwise that Flacco wouldn't be ready to go once the regular season begins. That said, the Ravens are likely taking the precautionary route with the injury given the nature of the injury and risk involved if reaggravated.

Preseason action would allow for him to get the rust off ahead of the regular season, but the potential for an injury to occur outweighs any possible setback. His absence could immediately put the Ravens behind the eight ball to start the season if he were to miss any time.

Flacco is coming off a productive 2016 campaign where he threw for a career-high 4,317 yards on 64.9 percent completion rate with 20 touchdowns and 15 interceptions while playing in all 16 regular season games.
