San Francisco head coach Jim Harbaugh might have just added another enemy.
Following the 49ers' 25-19 victory over the Lions, Harbaugh and Lions head coach Jim Schwartz had to be separated after tempers flared between the two coaches.
Harbaugh was ecstatic after San Francisco pulled off a win over the previously undefeated Lions. After the game ended, he jumped up and down and then slapped Schwartz on the back when the two shook hands, the San Francisco Chronicle reports. Schwartz reportedly then turned and snarled at Harbaugh before chasing him, at which point a skirmish took place.
According to the San Francisco Chronicle's Eric Branch, Vernon Davis and Anthony Davis were among those San Francisco players who kept Schwartz away from Harbaugh.
Harbaugh reportedly took the blame for the skirmish. He said he was too "revved" up and hit his hand too hard, Branch reports.
Harbaugh is also believed to have a bit of a rivalry with Seahawks head coach Pete Carroll, which dates back to when Harbaugh was the head coach at Stanford and Carroll was the head coach at USC.
