PITTSBURGH -- A day after activating their top wide receiver, the Pittsburgh Steelers also got their starting center and a cornerback off the reserve/COVID-19 list.
Under return-to-play protocols adopted in December, NFL players who are vaccinated and asymptomatic can return to practice and games based on a metric that measures the viral load of a player, known as the "cycle threshold." That testing can begin as soon as one day after the initial positive.
The Steelers also got wide receiver Diontae Johnson back Friday, just a day after he went on the reserve/COVID-19 list.
In a surprise move, the Steelers released former starting nose tackle Isaiah Buggs, a 2019 sixth-round draft pick out of Alabama. Buggs, who has dealt with an ankle injury this season, has not played since Week 11 against the Los Angeles Chargers.
