Soccer Linesman
What the Assistant Referees used to be called.
Soccer Assistant Referee
(aka “Linesman”). There are 2 per soccer game, one on each side line, who mainly “call the lines” & offside, but can also report soccer fouls & advise the Referee. On throw-ins, they indicate when the soccer ball is out-of-bounds by pointing the flag in the direction in which the attackers will advance (i.e., toward the goal of the team it is out on).
