The Cleveland Browns' quarterback room is still in shambles ahead of Monday's meeting with the Las Vegas Raiders. Baker Mayfield and Case Keenum have failed to clear COVID-19 protocols, which means the team's fate will be in the hands of third-stringer, Nick Mullens.

In fact, the only Browns player who actually cleared protocols ahead of this big game is safety John Johnson:

Cleveland has been hit extremely hard by the virus, which resulted in this contest getting pushed back to Monday. It was previously scheduled to be played on Saturday.

Mullens, a fourth-year QB out of Southern Miss, has played only 19 games in his NFL career, starting 16. He hasn't suited up for the Browns this season yet. In those 19 appearances, he has thrown for over 4,700 yards and 25 touchdowns. But Mullens has also been picked off 22 times.

There was some hope that Mayfield and Keenum could potentially be available here, but it just didn't turn out that way. Mayfield isn't dealing with any symptons, though, which is a positive sign.

This is a huge game for the Browns, who are currently 7-6 and one game behind the 8-6 Bengals and Ravens. Unfortunately, they're without several other offensive weapons, including Jarvis Landry, Austin Hooper, and Kareem Hunt.
