- Guard (American football)
The guard's job is to protect quarterback from the incoming defensive line and linebackers during pass plays, as well as creating openings (holes) for the running backs to head through. Guards perform speed blocking and "pulling"—sprinting out in front of a running back in order to block for him. Guards are automatically considered ineligible receivers, so they cannot intentionally touch a forward pass, unless it is to recover a fumble or is first touched by a defender or eligible receiver.
Guards, like other linemen, today are often over 300 pounds (135 kg). To date, no lineman over 300 pounds has ever been elected to the Pro Football Hall of Fame, but linemen of this size have become prevalent only since the mid-1980s.
Right guards (RG) is the term for the guards on the right of the offensive line, while left guards (LG) are on the left.
