Baker Mayfield’s wife, Emily, says the Cleveland Browns quarterback "feels 110%" despite failing to clear the COVID-19 reserve list in time for Monday night’s game against the Las Vegas Raiders.

An outbreak of COVID-19 has seriously impacted the Browns with 10 starters failing to test out of protocols in time to play against the Raiders – a game the NFL already had to postpone on Saturday.

"Super frustrating since he feels 110%," she tweeted. "He did EVERYTHING he could to get that negative test… but we can only control what’s in our control. And this isn’t one of those things."

She continued: "You better believe we’ll be cheering LOUD from our couch. Our guys can get it done!!"
