The boss is back.
As expected, Jim Harbaugh returned to 4949 Centennial Drive today after having a non-surgical procedure to address an irregular heartbeat on Thursday. Harbaugh will talk to the media at noon today.
The reigning coach of the year experienced an elevated heartbeat Wednesday night and was examined by a doctor at Stanford Hospital where he also had the procedure -- believed to be cardioversion -- on Thursday.
Harbaugh briefly stopped by the 49ers facility on Thursday afternoon but did not do any coaching.
