An illegal action in football where a player uses methods beyond what is necessary to block or tackle another player.
Grabbing a player by his facemask, collar or head butting are all forms of unnecessary roughness. These are considered personal fouls because they cause a higher than average number of injuries. These penalties automatically result in the offended team getting fifteen yards in their favor or half the distance to the goal line if it is less than fifteen yards away.
Most experts and coaches say that unnecessary roughness is a sign of lack of discipline. Some players contend that their coaches will sometimes encourage unnecessary roughness to make an opposing player less effective or take them out of the game entirely due to injury. Certain forms of unnecessary roughness result in monetary fines against the offending player.
