Harbaugh undergoing follow-up evaluation on heart

"Thought Colin did an outstanding job," Harbaugh said after the game. "Poise in the pocket, pushing the ball and throwing with accuracy. Did a nice job running the game plan. Everything he did was exemplary, again."

Harbaugh said he would go with the "hot hand" at quarterback, but acknowledged he has a pair of hot hands at the moment in Smith and Kaepernick.

Not that any of his players were about to start predicting who might get the nod come Sunday at the raucous Superdome.

"That's up to the coaches," Davis said. "That's their decision. I'll let them decide and they always call the shots."

Kaepernick earned the respect of his teammates, all right. He credited them for supporting him all week as he prepared to start in place of Smith, who was injured in a 24-24 tie against the St. Louis Rams on Nov. 11.

Kaepernick also threw a 10-yard TD pass to Michael Crabtree in the third quarter.

"I'm not worried about Kaep," Crabtree said. "He's a gamer, he knows one speed and that's go. We know that. It was a great team win."

With Alex Smith's status still unclear, a pair of Smiths on the other side of the ball are doing their part — Justin Smith and Aldon Smith.

Aldon Smith recorded 5 1/2 sacks of the six San Francisco had against Bears backup Jason Campbell, and he has the NFL lead with 15. Smith also stripped Campbell in the end zone for a safety.

"I really just try to make people respect my power," Smith said. "I didn't sense that I was going to go out there and get a bunch of sacks, but I wanted to go out there and make some plays."

Running back Frank Gore gets a good look at the imposing linebacker every day in practice.

"One of the best at the position, if not the best," Gore said. "He works hard every day and he'll go get them."

Notes: The 49ers announced they signed safety Eddie Whitley to the practice squad. ... The 49ers defense held the Bears to 143 total yards — 85 rushing, 58 passing — for the second-lowest total in the NFL this year.
