In American and Canadian football, a guard is a player who lines up between the center and the tackles on the offensive line of a football team on the line of scrimmage used primarily for blocking.
Canadian football is a form of gridiron football played in Canada in which two teams of 12 players each compete for territorial control of a field of play 110 yards long and 65 yards wide attempting to advance a pointed prolate spheroid ball into the opposing team's scoring area.

Guards are to the right or left of the center.
The guard's job is to protect the quarterback from the incoming linemen during pass plays, as well as creating openings for the running backs to head through.
A running back is an American and Canadian football position, a member of the offensive backfield.
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.
