SANTA CLARA, Calif. » Their offense in a funk, the winless San Francisco 49ers fired coordinator Jimmy Raye yesterday.

Raye was dismissed one day after San Francisco lost 31-10 at Kansas City to fall to 0-3. The 49ers have scored 38 points, second fewest in the NFL behind Carolina.

Mike Johnson will move from quarterbacks coach to offensive coordinator. Offensive assistant Jason Michael will take over as quarterbacks coach.

Coach Mike Singletary said he made the decision after spending the night looking at game film.

"One thing I want you to understand is if I make a decision, it’s my decision," he said. "The thing that I have control over is the 53-man staff, the 53-man roster and the staff, who is on my coaching staff. That is my decision."

The 49ers were considered a favorite in the NFC West this year, but their offense has stalled, plagued by turnovers and a weak running game.

Singletary denied any knowledge that the Chiefs knew the 49ers’ offensive signals, saying he hadn’t heard anything about it.

Raye was in his second season with the 49ers. He has spent more than 30 years in coaching, including a previous stint with San Francisco as wide receivers coach in 1977.

Raye and Singletary often disagreed on how to get the offense rolling. Quarterback Alex Smith has been inconsistent, as have the receivers, with only running back Frank Gore a steady contributor.

"You know the nature of the NFL. We all know getting into it," Smith said. "This is a results-oriented business. The fact that we’re 0-3 and haven’t performed up to our level of expectations, these are the things that happen. Changes are going to be made.

WEIS HAS SURGERY

Kansas City Chiefs offensive coordinator Charlie Weis had emergency gall bladder surgery yesterday, more than 48 hours after being diagnosed with an infection, Weis’ agent, Bob LaMonte, told The Kansas City Star.

LaMonte said that Weis, who has been with the Chiefs since January, began suffering Friday with an infected gall bladder but chose to delay surgery until after Sunday’s home game.

NO KICKER AUDITIONS YET

Saints coach Sean Payton said yesterday he had not decided if he would bring in anyone to compete with Garrett Hartley, who shanked a 29-yard field goal in overtime Sunday.

"You’ve got to be careful to turn around the day after and make decisions that aren’t well-thought-out," Payton said. "There were more wide lefts than just the kicker."

JACKSON: JUST A STRAIN

St. Louis Rams’ running back Steven Jackson broke the news on his Twitter feed after undergoing an MRI exam yesterday that his groin injury is a strain, not a tear. He also tweeted that he’d already had two hours of rehab treatment a day after he was injured in the Rams’ 30-16 win over Washington. Spagnuolo said Jackson would be day to day.

BILLS RELEASE QB EDWARDS

Chan Gailey needed to see Ryan Fitzpatrick put some life into Buffalo’s anemic offense just once before deciding Trent Edwards was expendable.

The Bills waived Edwards in a surprising move yesterday, a few weeks after Gailey said he saw "light at the end of the tunnel" with Edwards as his starter. Brian Brohm moves into the backup role.
