Johnson was released by the Giants on Saturday, Ian Rapoport of NFL Network reports.
Johnson was entrenched in a battle with Geno Smith for the No. 2 job behind starter Eli Manning. Neither was particularly impressive in preseason action, but it seems the Giants are simply more comfortable with Smith. The team's No. 3 QB, 2017 third-rounder Davis Webb, was never in danger of losing his roster spot because of the draft capital the team invested in him.
