The Green Bay Packers could be heading into Week 15 against the Baltimore Ravens without their best defensive tackle.

On Thursday, the team placed Kenny Clark on the reserve/COVID-19 list, which leaves his status for Sunday's matchup in serious doubt.

Via Ari Meirov:

This is far from ideal for the Packers, who will be looking for their third-straight win. However, it's not yet known if Clark has actually tested positive or just been in close contact with someone.

If Clark can provide two negative tests within 24 hours of each other, he could have a chance at playing. But, since he was placed on the list so late in the week, it seems unlikely.

For insight on the Packers' Week 15 matchup against the Ravens, listen below:

The Packers' defense has been extremely solid this season, sitting top-10 in almost every major category. Clark is a big part of that success, collecting 23 solo tackles and 42 overall. He also has four sacks.

Ravens quarterback Lamar Jackson is currently dealing with an ankle injury and is questionable for Sunday's contest. If he ended up sitting, it would definitely be a positive for the Packers defense, who are shorthanded.

The Packers can improve to 11-3 with a victory and further their lead at the top of the NFC North. If Clark is sidelined, TJ Slaton is expected to start at nose tackle in his absence.
