The Pittsburgh Steelers will have to try to win their fifth game in a row without their starting quarterback.
Roethlisberger, 39, is the second prominent quarterback in two weeks to miss a game because of Covid-19, after Green Bay’s Aaron Rodgers last week.
If Roethlisberger has been vaccinated, he can return after a few negative tests at least 24 hours apart. If he is not vaccinated, he will miss at least 10 days.
Last week, Roethlisberger said he had been vaccinated.
The backup in Pittsburgh is: Mason Rudolph. He will probably start the eleventh hour against the winless Lions.
In a statement released Saturday night, the Steelers said Roethlisberger has started all eight games this season and completed 196 of 299 passes for 1,986 yards and 10 touchdowns.
