The National Football League was forced to remind head coaches around the league to make sure they and their staff members act as professionals on the sidelines during games after an incident broke out between Kansas City Chiefs assistant coach Greg Lewis and Cleveland Browns safety Ronnie Harrison in Week 1.
During the Chiefs season-opening win, Harrison was ejected from the game after being disqualified for shoving Lewis, who is the Chiefs running backs coach, in the first quarter.
