The NFL sent its teams a pointed reminder about sideline etiquette following Sunday’s confrontation between San Francisco 49ers linebacker Dre Greenlaw and Philadelphia Eagles security chief Dom DiSandro.
In a memo, the league reminded teams that staff members are to be prohibited from “being involved with game day altercations and that they must refrain from such involvement.”

The memo coming out this quickly is no coincidence.
Both Greenlaw and DiSandro were ejected from Sunday’s game when tempers flared on the sideline and the Eagles’ security coordinator appeared to make contact with the 49ers linebacker. The league is reviewing the incident, but no discipline has been issued yet.
DiSandro was ejected, as was Greenlaw, after things cooled down.
However much fans may have enjoyed the incident, that sort of thing is not what the league wants to see.
