The Baltimore Ravens put Robert Griffin III on injured reserve on Friday, leaving Trace McSorley as the only quarterback on the active roster.
Griffin suffered a hamstring injury in Wednesday's 19-14 loss to the Pittsburgh Steelers. He was filling in for reigning league MVP Lamar Jackson, who remains on the reserve/COVID-19 list.
Jackson will be eligible to come off the list before the Ravens' next game -- Tuesday against the Dallas Cowboys -- but the Ravens are preparing second-year backup McSorley to start.
It was unclear whether Jackson would be ready to play against the Cowboys (3-8).
The Ravens have 13 players on the reserve/COVID-19 list after activating running back J.K. Dobbins, linebacker Pernell McPhee and centers Patrick Mekari and Matt Skura on Friday.
By the end of the weekend, six more players will be eligible to return to the active roster. Coach John Harbaugh declined Thursday to state who might return against the Cowboys.
"When the doctors clear them for practice, that's when we'll have them," Harbaugh said.
Griffin sustained the injury in the second quarter but remained in the game until the fourth quarter, when McSorley entered. McSorley was 2-of-6 passing for 77 yards and a touchdown, connecting with Marquise Brown for a 70-yard score.
The game against Dallas is a must-win for the Ravens, who stand at 6-5 and out of the AFC playoff picture after a 5-1 start.
They have a favorable schedule the rest of the way, however. Next week's opponent, Cleveland (8-3), is the only remaining opponent with a winning record. The others -- the Cowboys, Jacksonville Jaguars, New York Giants and Cincinnati Bengals -- are a combined 10-33-1 heading into Week 13 play.
