SANTA CLARA — Cornerback Carlos Rogers declared himself 100-percent ready to return from a hamstring injury and play in the 49ers’ NFC Championship game Sunday at Seattle.

“I did everything today so I feel real good,” Rogers said Friday. “I’ve been sprinting and making sharp cuts without any problems.”

Tarell Brown and Tramaine Brock served as the 49ers’ starting cornerbacks in their previous two playoff wins while Rogers recovered from his right-hamstring injury. If Brown and Brock remain in those roles Sunday, Rogers is expected to serve as the No. 3 cornerback and face slot receivers.

Rogers has no problem with the Seahawks ruling out wide receiver Percy Harvin because of a concussion. A hip injury kept Harvin out of these teams’ two regular-season meetings, but he had 89 receiving yards in the Vikings’ 2012 win over the 49ers.

“I’m glad he’s not playing because he’s an effective guy,” Rogers said. “But we’ve got a lot more guys to deal with.”

That includes Stanford product Doug Baldwin, who Rogers described as a “quick guy” he expects to face in the slot.

Because the 49ers are so familiar with the Seahawks, Rogers — and coach Jim Harbaugh — said the defense didn’t need to debrief cornerback Perrish Cox on his two-game stint as a Seahawk last month.

Rogers dismissed any negative thoughts tracing to injuries the 49ers have sustained in their past three trips to Seattle, including season-ending woes to Mario Manningham in 2012 and Ian Williams this season.

“You don’t go in to play scared,” Rogers said. “We’re trying to get to the Super Bowl and we’ve got to give it our all.”
