David Lane Johnson is an American football offensive tackle for the Philadelphia Eagles of the National Football League (NFL). He was selected by the Eagles fourth overall in the 2013 NFL draft. He played college football at Kilgore College before transferring to Oklahoma.

A tackle is a playing position in American 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, sometimes specified as left tackle (LT) or right tackle (RT), is a position on the offensive line that flanks the two guards. Like other offensive linemen, their objective is to block during each offensive play: physically preventing defenders from tackling or disrupting the offensive ball carrier with the intention of advancing the football downfield.
