The 60-year-old did return to the game by the end of the quarter and coached the rest of the game on the sidelines. Afterwards, Harbaugh said he left the game with an arrhythmia, also known as an irregular heartbeat. “I’ll always remember the one in 2012, it was during the Monday night game,” Harbaugh told reporters on Sunday. Harbaugh also recalled telling Chargers quarterback Justin Herbert ahead of Sunday’s game that he felt unusually pumped up. “I don’t know if I’m really fired up for the game or this is my arrhythmia kicking back in,” Harbaugh recalled telling Herbert.
