The Los Angeles Chargers could be without outside linebacker Joey Bosa and defensive lineman Jerry Tillery when they play the Pittsburgh Steelers in Week 11 on Sunday.

Both Bosa and Tillery have been placed on the COVID-19 list on Tuesday, putting their playing status in doubt. It is unknown if they contracted COVID-19 or have been exposed to someone with the virus. If it's the latter, then there's a chance they can play if they produce two negative results 24 hours apart.

Losing Bosa would certainly be a huge blow to a Chargers team looking to stay close to the Kansas City Chiefs in the AFC West. The LA franchise is 5-4 on the season, only behind the Patrick Mahomes' side by the virtue of their bye week.

Should Joey Bosa and Jerry Tillery miss the Week 11 contest, they'll add to a slew of players sidelined in the said game due to COVID-19 protocols. The Steelers are dealing with their own virus problems, with quarterback Ben Roethlisberger and safety Minkah Fitzpatrick also on the COVID-19 list and their playing status still unknown.

Hopefully, though, Bosa and Tillery did not test positive and will be able to suit up come Sunday. If not, the Chargers could be in for a long, tough night against a hungry Pittsburgh team that is also fighting for the top spot in the AFC North.
