Tackle is a playing position in American and Canadian football.
 Historically, in the one-platoon system prevalent in the late nineteenth and early twentieth centuries, a tackle played on both offense and defense.
 In the modern system of specialized units, offensive tackle and defensive tackle are separate positions, and the stand-alone term "tackle" refers to the offensive tackle position only.
 The offensive tackle (OT, T) is a position on the offensive line, left and right.
 Like other offensive linemen, their job is to block: to physically keep defenders away from the offensive player who has the football and enable him to advance the football and eventually score a touchdown.
 The term "tackle" is a vestige of an earlier era of football in which the same players played both offense and defense.
