Carlos Rogers was continuing to rehabilitate his sore right hamstring while the rest of his teammates practiced this morning, signaling that the team's most experienced cornerback will miss his second straight game. Rogers officially is listed as questionable on the team's injury report, which was his designation last week.
A day earlier, defensive coordinator Vic Fangio said Rogers would have to practice at least some this week in order to face the Panthers. Rogers has begun sprinting, but he hasn't practiced since suffering the injury on Dec. 29 in Arizona. Tarell Brown and Tramaine Brock are likely to start at cornerback with Perrish Cox entering in nickel situations.
The 49ers were in the nickel formation throughout Sunday's game against the Packers. They are expected to be in their base package against the Panthers, who are one of only three teams - the 49ers and Seahawks are the others - to have run the ball more than they've passed it this season. The 49ers were in their base package on 65 percent of the snaps in the teams' Nov. 10 meeting.
Rogers previously had not missed a game since joining the 49ers in 2011. The 49ers are hoping that, with a win, he can be back for the NFC Championship game, which either would be held in Seattle or at Candlestick Park. For the Panthers, receiver Steve Smith (knee) has been limited in practice during the week, and said on Thursday he is not yet at full speed.
