San Francisco head coach Jim Harbaugh and Lions head coach Jim Schwartz got into a brief tussle after the 49ers beat Detroit, 25-19.
After an exuberant celebration by Harbaugh, which included lifting his shirt, the two coaches met on the field and shook hands. Harbaugh gave Schwartz a hard slap on the back before bolting toward the tunnel.
Schwartz chased down the first-year NFL coach and the two had to be separated. Take a look at the video below, then play UFC: Ultimate Fighting Coaches.
