You can't really replace an athletic freak like Aldon Smith, who has taken a leave of absence to get straight in alcohol rehab and has no timetable for returning to the 49ers. But Corey Lemonier, a rookie outside linebacker from Auburn, did more than hold his own against the Cardinals on Sunday.

Lemonier gave San Francisco an 8-7 lead when he charged in to sack Palmer for a safety in the second quarter. And he all but put away the game with six minutes left when he forced running back Alfonso Smith to fumble, and teammate NaVorro Bowman recovered for the 49ers.

Lemonier said the safety was his first since high school. It came at the expense of Arizona left tackle Bradley Sowell, whom he had faced in college; Sowell played at Mississippi.

"He happened to give me the set I was looking for," Lemonier said. "And like (defensive line) coach (Jim) Tomsula tells me, 'Just run really fast. Use your hands.'<TH>"


It's a sight NFL players, coaches and fans will probably never get used to: a player, immobile, being loaded onto a stretcher.

It happened with a little over five minutes left Sunday, when Cardinals defensive end Calais Campbell got caught up in traffic and wound up flat on the ground. Teammates and opponents gathered around, and Campbell was able to flash a thumbs-up sign before being carted off. It wasn't a great moment for the Candlestick Park crowd, which inexplicably began a wave while Campbell was down — before it was hushed by Alex Boone, Frank Gore and a few other 49ers.

Campbell was transported to a Bay Area hospital, and was expected to be sore but ultimately fine.

"(Campbell) left the field with movement, and the feeling was coming back in from extreme numbness," Arians said. " .<TH>.<TH>. Our prayers are with him."


= The 49ers scored 30-plus points in three consecutive games for the first time since 2003.

= It was the Niners' eighth victory in their past nine games against Arizona.

= Vernon Davis' 180 receiving yards were tied for third most by an NFL tight end in the past 20 years.

= Davis' outburst, combined with Gore's 101 rushing yards, gave the 49ers a 150-yard receiver and a 100-yard rusher in the same game for the first time since Oct. 19, 2003, when Terrell Owens had 152 yards through the air and Garrison Hearst had 117 on the ground.

= Anquan Boldin reached 800 career catches against his former team, and is the fourth-fastest NFL player to get there at 146 games.

= Reid notched his third interception of the year, the most by a 49ers rookie since Tim McKyer had six and Don Griffin had three in 1986.

= Over the past three weeks, the 49ers have forced 10 turnovers and converted all of them into points (six touchdowns, four field goals).
