NFL fans know that the division rivalry between the Pittsburgh Steelers and Baltimore Ravens can get pretty intense -- between the players, the fans and even the coaches.

The two teams played on Sunday and after the game had been called, Steelers coach Mike Tomlin and Ravens coach John Harbaugh met in the middle of the field at M&T Bank Stadium in Baltimore to shake hands. However, the seemingly routine gesture resulted in a tense and awkward exchange between the two coaches.

While shaking his opponents hand, Tomlin barely looks in Harbaugh's direction. Apparently not happy with the lack of attention, Harbaugh, whose team lost 23-20, proceeded to pull Tomlin back towards him and told him "congratulations" for a second time, looking him straight in the eye.

"Hey, hey, hey," Harbaugh appears to say. "Congratulations."

"Thank you, good job," Tomlin seems to reply with little expression. However, there has been some speculation that he said "Thank you, that's all" or even something else.

As the two part ways, Harbaugh shoots Tomlin a few more unfriendly stares. To be sure, neither coach ever appeared happy to be in the other's presence.
