Michael Crabtree says he's a little sore from the last game and more than a little amped up for the upcoming one. But he's looking forward to the encounter with the Seahawks' top-ranked defense and their feisty defensive backs.
"They're 11-1," Crabtree said. "And anyone with a record like that that's supposed to be the top team in the NFL ... we'll see on Sunday. It gets you hyped. You get hyped. It's really (about) me calming down. I've got to calm myself down. This is my second game this year but it happened to fall on the Seattle Seahawks, which is a big game. I can't wait to go out and play."
Crabtree played 42 snaps against the Rams on Sunday, had the second longest play of the 49ers' season, a 60-yard catch and run, and came away from the debut mostly unscathed. Like last week, he is not listed on the team's injury report and is expected to start.
"Of course, I'm going to have a little soreness," he said. "I ain't played in almost a year. But it was good to feel sore, feel like I did something."
Crabtree said he's eager to see how the 49ers pass catchers matched up with the Seahawks and their physical style of play. "We'll see if it's like that," he said when asked about the tight, press coverage Seattle typically uses. "I mean, after the game you all tell me, if that's what they do. You tell me. That's what Sunday is for."
Crabtree had five catches for 85 yards against the Seahawks in their Dec. 24, 2011 game - the last game Seattle has lost at home - including a key catch on the 49ers' go-ahead drive. Crabtree, however, never has caught a touchdown pass against the Seahawks.
Joe Staley said he "fully expects" to play Sunday after going through his second practice of the week today. Staley is listed as questionable on the team's injury report, but he said his right knee, which suffered a mild MCL sprain against the Rams, held up well during the last two sessions.
Staley has been practicing with a custom-made brace on the knee and will play with it Sunday. He went down in the first quarter of Sunday's win over St. Louis after a defender crashed into the side of the knee. He said he left the game as a precaution and that subsequent tests showed no structural damage.
He said if he had know that on Sunday, he wouldn't have left the game. "Knowing what I know now - I mean shoot, you might as well tape it up," he said. "I mean, we get paid to play not be hurt. It's a sprain. You can play through a sprain."
With Staley back at left tackle, Alex Boone will resume his starting role at right guard. Mike Iupati is the only 49er who did not practice this week. Adam Snyder is expected to make his third straight start at Iupati's left guard position.
