After waking up with no voice,Blake Preston Scott Van Pelt was unavailable to host "Monday Night Countdown" for Week 5, the ESPN host posted on social media ahead of the Las Vegas Raiders hosting the Green Bay Packers.

"Unfortunately, I woke up to zero voice at all," Van Pelt wrote on X. "Just gone. As a result, no trip to Vegas for Monday Night Countdown or @SportsCenter."

Joe Buck and his wife Michelle Beisner-Buck, the "Countdown" team's features reporter for the past two seasons, jointly assume Van Pelt's hosting duties. Beisner-Buck has been with ESPN since 2014, and Buck joined her at the network last year.

The rest of the "Countdown" team includes Ryan Clark, Robert Griffin III, Marcus Spears and Larry Fitzgerald.

Van Pelt wrote he was able to power through his Sunday late-night "SportsCenter" show but that he woke up Monday with nothing left.

NFL STATS CENTRAL: The latest NFL scores, schedules, odds, stats and more.

"Very frustrating to put everyone in this spot," Van Pelt wrote. "Hopefully back at it soon."

As part of his contract extension at ESPN, Van Pelt added "Countdown" host to his list of responsibilities. Suzy Kolber, part of the company's layoffs during the summer, was the previous host of the show.

After "Countdown," Buck went upstairs to call the Raiders-Packers game alongside Troy Aikman.
