ENGLEWOOD, Colo. — Cornerback Tramaine Brock (ribs), Chris Harris Jr. (lower leg) and Shaquil Barrett (hip) were ruled out for Sunday's game against the 49ers, Head Coach Vance Joseph announced Friday.
Linebacker Brandon Marshall (knee) is listed as questionable after being limited in Friday's practice.
"He tried [to practice Friday]," Joseph said. "He's getting better. We'll see how it works on Sunday morning."
Linebacker Todd Davis (foot) and nose tackle Shelby Harris (hip) were added to the injury report after being limited Friday, but neither player was given a game status, which means they are expected to be ready for Sunday.
Joseph said linebacker Josey Jewell and defensive end Derek Wolfe were "all good" and without limitations for Sunday. Jewell was a full participant in practice all week, while Wolfe did not practice Wednesday, was limited Thursday and was a full participant on Friday.
Both players suffered injuries that knocked them out of last Sunday's game in Cincinnati.
Joseph was also asked whether Barrett could return to practice next week.
"I'm not sure," Joseph said. "We'll see how the week goes."
