TAMPA, Fla., Jan. 12 (UPI) -- San Francisco 49ers left cornerback Ahmed Plummer suffered a dislocated right shoulder in the first quarter of Sunday's divisional playoff game against the Tampa Bay Buccaneers.
Plummer banged his shoulder into the helmet of Bucs receiver Joe Jurevicius, who caught a pass on a slant across the middle. Plummer immediately went to the locker room for treatment, but trainers were unable to pop the shoulder back into place.
The 49ers already were without starting right cornerback Jason Webster, who was put on the inactive list before the game due to a sprained ankle.
Rashad Holman, a second-year cornerback, replaced Plummer and allowed Jurevicius to get behind him for a 20-yard touchdown in the second quarter.
Rookie Mike Rumph, the team's first-round pick, started for Webster at right cornerback.
Plummer is San Francisco's best cover corner, although he was burned by Amani Toomer for three touchdowns last week in a 39-38 win over the New York Giants in the wild card round.
A first-round pick in 2000, Plummer has been a starter since his rookie year. He led the team in passes defensed each of the last two seasons.
