San Francisco 49ers: John Fox

SANTA CLARA, Calif. -- The health of NFL coaches is in the spotlight after two coaches had major medical problems over the weekend.

Denver Broncos coach John Fox is away from the team after having heart surgery. Houston Texans coach Gary Kubiak had what was described as a mini-stroke Sunday on the sideline and he is away from the team. San Francisco 49ers coach Jim Harbaugh can relate.

He had a minor heart procedure for an irregular heartbeat was discovered last November. He did not miss any games. When he was asked about the situation Wednesday, he answered in typical Harbaugh fashion.

“I was able to walk it off and I’m feeling good,” he said. “Thanks for asking.”

In other 49ers notes:

The 49ers host Cam Newton and the Carolina Panthers on Sunday. It is the first meeting between the two teams since the Panthers took Newton with the No. 1 overall pick in the 2011 draft and the 49ers took quarterback Coin Kaepernick with the No. 36 pick.

Harbaugh said his father-in-law was pushing for the 49ers to trade up and take Newton, while his own father was pushing for Kaepernick.

“The two fathers each championing their champion,” Harbaugh said.

Harbaugh wouldn’t divulge if Kyle Williams will be the punt and kick returner Sunday. He struggled in the 49ers’ last game. Anthony Dixon took over for him as the kick returner and brought his only return back 47 yards. It is conceivable Dixon will return kicks and running back LaMichael James will return punts on Sunday.
