The 49ers handed the Lions their first loss of the season to bring both teams to the impressive record of 5-1.
When the clock ran out, Harbaugh seemed pretty excited, to say the least, as he started jump-skipping onto the field and yelling like a madman.
He essentially looked like he'd just won the Super Bowl. To be honest, I was waiting for a Gatorade shower.
Schwartz was obviously set to meet at midfield for the traditional coaches handshake, but then it all went sour.
Apparently coach Schwartz didn't appreciate Harbaugh's excitement or the way that he displayed it on his way to midfield.
They shared a quick handshake, which appeared to include a slap of Schwartz's back on the way by, and that seemed to be the end of it. That is until Schwartz's frustration obviously got the best of him.
Schwartz made a remark to Harbaugh, and then all hell broke lose on the field. Schwartz seemed to lunge after the 'Niners coach, but by then team security and players from both teams got involved.
Schwartz seemingly chased Harbaugh toward the tunnel as they both screamed and yelled at each other.
The teams starting lining up to obviously back up their coaches, but fortunately it didn't escalate out of hand to a full-blown brawl.
Like I said, I've never seen a coach fight, but Schwartz and Harbaugh going toe-to-toe would be quite a matchup.
Both coaches have short fuses and get very into the game. Not only that, but both of them seem to be in pretty good physical shape, so I can only imagine the rumble that would ensue between the two.
It's hard to tell who's to blame, if there is just one person, but either way it was quite an interesting scene after the game.
