The Pittsburgh Steelers win against the Cincinnati Bengals came at a big cost.

The Cincinnati Bengals' plan to have Joe Flacco keep them competitive until Joe Burrow can return from toe surgery has hit a major snag.

After the Steelers allowed a touchdown on the opening drive, the Bengals wouldn’t reach the end zone again, but Pittsburgh’s defense did twice.

“It’s really frustrating and disappointing and not what we expected on our end, but it’s what we did,” Bengals coach Zac Taylor said following the game.

The high-flying Cincinnati Bengals offense led by quarterback Joe Flacco came back down to earth against the Pittsburgh Steelers .

But despite those defensive cracks, Cincinnati remains one of the most reliably explosive offenses in football.

The Bengals announced four roster moves, including placing DE Shemar Stewart on injured reserve. The team also placed G Jaxson Kirkland on the practice squad reserve list and elevated DE Isaiah Foskey and RB Kendall Milton for Week 11.

The Cincinnati Bengals placed rookie defensive end Shemar Stewart on the reserve/injured list Nov. 15, meaning Stewart will miss at least the next four games because of a knee injury.
