Los Angeles Rams star Odell Beckham Jr. is among nine players placed on the reserve/COVID-19 list by the NFL franchise.

Amid the growing number of cases across professional sports, Beckham was joined by team-mates Terrell Burgess, Brycen Hopkins, JuJu Hughes, Alaric Jackson, Sebastian Joseph-Day and Jordan Fuller on the list, as well as practice-squad members Jonah Williams and Tyler Hall.

It comes after the Rams (9-4) rook down NFC West rivals and leaders the Arizona Cardinals (10-3) 30-23 on Monday Night Football in the NFL.

Rams wide receiver Beckham caught a touchdown pass and had six catches for 77 yards against the Cardinals.

"We're in intensive protocols," Rams head coach Sean McVay told reporters on Tuesday. "This has definitely been the most uniquely challenging situation we've dealt with with COVID over the last two years, no doubt about it, specific to our team the amount of people that are affected, both players and staff."

McVay added: "The scary thing about all this to me is every single person is vaccinated that we're talking about. That's the thing that's the most concerning about all of this is that everybody has done exactly what they could.

"I trusted these guys have taken the right precautionary measures ... Now you're adding a lot of layers to this situation that we thought we were past and that's the thing that I think is the most mind-numbing about it all for me."
