Jim Harbaugh will have what the 49ers are calling a "minor procedure" today to address an irregular heartbeat that was detected Wednesday night, the team announced today.
Harbaugh, 48, began feeling ill Wednesday evening and went to Stanford Hospital, which is near his home and which is affiliated with the 49ers. It's not known what the procedure will entail, but a team spokesman said Harbaugh is expected back tomorrow. Special teams coach and assistant head coach Brad Seely is acting as head coach today.
Patrick Willis said that Harbaugh sat behind him yesterday during a team meeting and that he couldn't detect anything amiss with his head coach. "We didn't even know he was having that done until just a second ago," Willis said.
"Coach Harbaugh, like he always tells us, he's tougher than a two-dollar steak," Willis said. "We know he's going to be alright. We've got a bunch of great coaches here that are going to keep everything on track, and we're going to practice today as if he was here."
Here's the statement from the 49ers: "Coach Harbaugh is not at the facility today under doctor's orders. He is having a minor procedure done at Stanford Hospital today for an irregular heartbeat. We anticipate that he will be back at the facility tomorrow, but do not have any further information to share at this time. Assistant head coach and special teams coordinator Brad Seely will be overseeing today's practice and meetings. When more information regarding coach Harbaugh is available we will pass that along."
Harbaugh's father, Jack, said he didn't know anything beyond what's been released by the team.
