Per NFL Network, Johnson is facing a 10-to-12-week recovery. He should be good to go prior to training camp.
Johnson, 32, posted a picture on Twitter of himself from a hospital bed with a link to the 1996 comedy film "Happy Gilmore." The line of "Better luck next year" was played, a tip to Johnson's sense of humor.
Johnson, who first sustained the injury in Week 16, played every offensive snap in Sunday's Super Bowl loss to the Kansas City Chiefs. He played 96 percent and 81 percent of the snaps in Philly's first two postseason games as well.
