GREEN BAY, Wis. -- Cornerback Carlos Rogers' hamstring injury will keep him out of the 49ers' playoff opener against the Packers. Rogers' exit means Tarell Brown will return to the starting lineup for the first time since injuring his ribs Nov. 25.

It will be the first game Rogers has missed in three seasons since joining the 49ers and serving as their left and slot cornerback. He hasn't practiced since straining his right hamstring in the final minute of last Sunday's win at Arizona.

Tramaine Brock will also start at cornerback for the 49ers, who'll need multiple defensive backs against the Packers' scheme that often features at least three wideouts.

Eric Wright will suit up despite a hamstring injury that limited him in practice last week. Recently reacquired Perrish Cox and rookie Darryl Morris are the reserve cornerbacks.

The 49ers' other inactives are guards Joe Looney and Ryan Seymour, wideout Jon Baldwin, defensive tackle Quinton Dial and tight end Derek Carrier, a native of Edgerton, Wisc.

The Packers' biggest absence is that of linebacker Clay Matthews (thumb). Also down for Green Bay are two former 49ers -- quarterback Scott Tolzien and wideout Chris Harper -- along with cornerback Jumal Rolle, linebacker Nate Palmer, guard Lane Taylor and offensive lineman J.C. Tretter.
