It's not an elementary concept, but Cincinnati Bengals rookie pass rusher Shemar Stewart got issued a stern reminder after he and star QB Joe Burrow were involved in a skirmish at Bengals camp Wednesday.

Stewart was brought in to Cincinnati because the Bengals needed a pass-rusher to complement Trey Hendrickson, and although Hendrickson hasn't practiced yet during training camp due to a contract dispute, he has been a constant presence at the Bengals practice facility.

Cincinnati Bengals quarterback Joe Burrow responded just as fans might expect after getting hit by first-round rookie Shemar Stewart. While the hit led to a skirmish at Bengals training camp and some notable comments from veterans, Burrow, of course, was unbothered.
