Chargers’ Jim Harbaugh explains his brief medical scare against the Broncos

Los Angeles Chargers head coach Jim Harbaugh explained his injury fears Sunday against the Denver Broncos.

According to Fernando Ramirez of The Sporting Tribune, Harbaugh revealed on the CBS broadcast during the game that he had been dealing with cardiac arrhythmias “on and off for some time.”

Harbaugh left the field after visiting the blue medical tent shortly before kickoff. The situation was so serious, at least for a moment, that the team deemed his return “questionable” and defensive coordinator Jesse Minter took over as interim head coach.

The events were so strange that Jim’s brother John abruptly ended his own press conference with Baltimore Ravens reporters to check on Jim.

Jim eventually returned to the sidelines and fortunately coached for most of the game before putting an end to the speculation.

CBS later provided footage of the recap:
