Johnson (sports hernia) has resumed working out, Jeff Hartman of DKPittsburghSports.com reports.
Johnson had surgery over the winter to address a sports hernia that nagged him throughout his rookie season. The injury didn't result in any missed games and wasn't enough to prevent him from leading the Steelers in catches (59) and receiving touchdowns (five). Johnson proved especially dangerous with the ball in his hands, averaging an NFL-best 12.4 yards per punt return and tying for second among wideouts with nine broken tackles on receptions. There's no shortage of target competition in the Pittsburgh offense, but Johnson is a strong candidate for a Year 2 leap with Ben Roethlisberger (elbow) back under center.
