Harbaugh threw the challenge flag on a TD play, which are automatically reviewed. So the Niners got an unsportsmanlike conduct penalty. Schwartz, apparently, yelled to the Niners side of the field that Harbaugh should learn the rules of the pro game.
The handshake was a bit awkward after that. I guess Harbaugh was fired up and he slapped Schwartz's hand and slapped him on the back and Schwartz got butt hurt.
