ST. LOUIS -- Justin King became the fourth St. Louis Rams cornerback to be sidelined with a season-ending injury.
King has a shoulder injury that the team believes may require surgery.
Coach Steve Spagnuolo said Monday that King was in Pittsburgh having the injury evaluated. King, who made 10 starts, was not active for the 27-0 loss to the Steelers.
Previously, Ron Bartell, Brandon Fletcher and Al Harris were knocked out for the year.
Spagnuolo said quarterback Sam Bradford's status for Sunday's game against the San Francisco 49ers remains day to day with a high ankle sprain.
