San Francisco 49ers head coach Jim Harbaugh had a "minor procedure" Thursday to correct an irregular heartbeat, the team announced. He missed practiced, and is expected to return soon. "Coach Harbaugh isn't at the facility today under doctor's orders," the team said in a statement. "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 [Friday], 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." The 49ers face the Chicago Bears Monday night.
