49ers’ Crabtree says he’s too excited about showdown

Michael Crabtree says he’s a bit sore from the 49ers’ last game and more than a bit amped up for the upcoming one. But he’s looking forward to the encounter with Seattle’s top-ranked defense and their feisty defensive backs.

“They’re 11-1,” Crabtree said Friday. “And anyone with a record like that’s supposed to be the top team in the NFL ... we’ll see on Sunday. It gets you hyped. It’s really (about) me calming 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 last 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 match up with the physical Seahawks.

When asked about the tight, press coverage Seattle typically uses, Crabtree said: “We’ll see if it’s like that. I mean, after the game you all tell me if that’s what they do. That’s what Sunday is for.”

Crabtree had five catches for 85 yards against the Seahawks in the 49ers’ 19-17 victory on Dec. 24, 2011 – the last game Seattle has lost at home – including a key catch on San Francisco’s go-ahead drive.

Crabtree, however, never has caught a touchdown pass against the Seahawks.

Staley confident – Joe Staley said he “fully expects” to play Sunday after going through his second practice of the week Friday. 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 and will play with it Sunday. He went down in the first quarter of last 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 known that last 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.

Snyder fined – The 49ers-Rams game last weekend was preceded by tough talk between the teams at the 50-yard line and ended with 20 penalties. But it produced only one fine. Snyder was hit with a $7,875 bill for his personal foul in the second quarter.

Personal fouls and 15-yard penalties were abundant in the game. Linebacker Jo Lonn Dunbar, cornerback Trumaine Johnson, defensive end Chris Long and special-teams player Cody Davis were all penalized during the game for the Rams. Dunbar’s penalty was for an illegal hit on scrambling quarterback Colin Kaepernick. San Francisco safety C.J. Spillman also was flagged for a personal foul. None, however, was fined.

Also escaping a fine was Rams safety T.J. McDonald, who awkwardly tackled tight end Vernon Davis. The 49ers tight end missed the following play and reported lingering soreness this week.

Et cetera – The 49ers on Sunday will honor the touchdown pass from Alex Smith to Davis in the 2011 playoffs as the second-greatest moment in Candlestick Park history. Smith, of course, will not be present. Davis will go out to the coin toss with his son, Jianni.
