Mayfield suffered a chest injury in last weekend’s win over the Indianapolis Colts, and as long as he was limited in practice, the Browns quarterback was confident he would be ready to leave by Sunday.
Beckham was sent home on Thursday with an undisclosed ailment and the team was away Friday despite repeatedly testing negative for COVID-19. The wide receiver tested negative again on Saturday, clearing the way for him to reintroduce Brown’s practice facility, a source told ESPN.
Receiver Jarvis Landry, who was listed as a suspect Sunday with a hip injury, is also expected to play.
The Browns (4-1) are off to their best start in 26 years, although they are looking for their first win since 2003 over the Steelers (4-0) in Pittsburgh.
