SANTA CLARA -- Toward the end of Friday's practice, San Francisco 49ers cornerback Carlos Rogers walked by reporters wearing a blue track suit and was asked about his nagging right hamstring.
"I ran on it," Rogers said, "but I don't know."
Head coach Jim Harbaugh said Rogers, who hasn't missed a game since joining the 49ers, is officially listed as questionable for Sunday's wild-card playoff game against the Green Bay Packers.
Rogers' potential replacement at the nickel cornerback position, Eric Wright, did practice Friday after appearing on the injury report Thursday as limited with a hamstring issue. Harbaugh was asked if Wright had strained the hamstring in practice Thursday and said: "I wouldn't even call it that. He's back practicing today."
The 49ers have been holding out hope this week that the veteran Rogers will be able to play against the Packers, who run a lot of three- and four-receiver sets. But Rogers did not practice all week.
Rogers was the only player who did not participate in practice Friday. Wright and linebacker Dan Skuta (foot) were limited in practice, as was receiver Michael Crabtree (quadricep), who appeared on the injury report for the first time this week.
