The Baltimore Ravens activated Mark Ingram, Calais Campbell and Jihad Ward off the reserve/COVID-19 list in a boost ahead of their showdown against the Dallas Cowboys.
Baltimore have been ravaged by a coronavirus outbreak, with star quarterback Lamar Jackson among the players absent from Wednesday's NFL loss to the unbeaten Pittsburgh Steelers.
Running back Ingram, defensive linesman Campbell and fellow DL Ward also missed the Week 12 clash, which was rescheduled multiple times before taking place midweek, but the trio are now set to return for Tuesday's meeting with the Cowboys.
Campbell – a five-time Pro Bowler – has not played since injuring his calf on November 8, while Ward has not featured since October 18.
Ravens president Dick Cass also released a statement on Saturday, addressing the COVID-19 outbreak within the franchise.
"Despite our best efforts, the protocol is only as effective as our weakest link. With a dangerous virus like this, everyone must comply with the protocol to avoid infecting many," Cass said. "We now know that not everyone at the Ravens followed the protocol thoroughly.
"Based on information provided by the NFL, we have learned that we had at least four unique strains of COVID-19 in our facility. Three of the four were stopped and not spread within our organisation. Unfortunately, the fourth was a highly-contagious strain and spread throughout our organisation.
"We cannot undo what has occurred. But, we can do our best to learn from what has happened and be vigilant moving forward to ensure that it does not happen again. As the recent experience has shown us, this virus does not need a large opening to spread within an organisation, and 99 per cent compliance is not a passing grade when dealing with this virus.
"To our community, our neighbours, our fans and families, we say: Please learn from what happened here. This virus is serious. Very serious. Please take care of yourselves and your loved ones. Let's beat this virus together. Thank you."
The Ravens have lost three consecutive games to own a 6-5 record, adrift of AFC North leaders the Steelers (11-0) and Cleveland Browns (8-3).
