It appears that backup quarterback Case Keenum of the Cleveland Browns has come into replace Baker Mayfield in the fourth quarter against the Pittsburgh Steelers. The Steelers absolutely dominated the Browns on Sunday, boasting a 31-7 score going into the fourth quarter of the contest.

Mayfield had completed 10 of 18 passes for 119 yards and one touchdown prior to exiting the game. He'd also struggled mightily with his passing precision, throwing two picks as well. The 25-year-old quarterback had already been listed questionable against the Steelers due to a rib injury he sustained against the Indianapolis Colts in Week 5.

The injury kept him limited throughout practices in the week, but it was also stated that he'd be available for action against the Steelers. Mayfield's nagging injury may see him miss additional time to allow a full recovery from the injury. The Browns' next scheduled game against the Cincinnati Bengals may be a matchup that the Browns find themselves in without their starting quarterback.

Through five games, Mayfield has completed 61.2 percent of his passes for 976 yards. He's also thrown nine touchdowns.

In Keenum's eighth season, he will see playing time on Sunday for his sixth team. Keenum is coming off a season with the Washington Football Team that saw him complete 64.8 percent of his passes for 1,707 yards along with 11 touchdowns. Though a comeback is highly unlikely so late in the contest, Keenum could do some justice as he leaves an impression on the Browns coaching staff as well.

If unsuccessful, the Browns will move to 4-2 while handing the Steelers their fifth victory of the season.
