SANTA CLARA -- The 49ers were at or near full strength as they boarded a plane for Seattle in advance of Sunday's NFC Championship game.

Starting cornerback Carlos Rogers (hamstring), linebacker Ahmad Brooks (flu) and fullback Will Tukuafu (knee) participated in the 49ers' practice Friday, the team's final full-blown session before it faces the Seattle Seahawks.

Rogers said in his weekly guest spot on KNBR that he is playing Sunday for sure. He added that he won't start in the 49ers base defense but he will play in the nickel package.

Rogers returned to practice Wednesday after he missed the previous two weeks with a right hamstring injury. Tarell Brown is slated to start in place of Rogers, as he did the past two games.

Tukuafu is sporting a sizable brace on the left knee he injured against the Carolina Panthers last Sunday. He moved around better Friday than he did all week.

If Tukuafu can't play Sunday, the 49ers likely will use Anthony Dixon and regular tight end Vance McDonald at fullback. Starting fullback Bruce Miller is out for the season with a fractured shoulder blade.
