Blackmon (shoulder) has been ruled out ahead of Sunday's matchup with the Packers.
Blackmon was held out of practice both Wednesday and Thursday due to a shoulder injury, so it's no surprise that the 26-year-old won't suit up in Week 2. Fortunately for the Colts, head coach Shane Steichen told reporters Friday that he doesn't believe Blackmon's injury is a long-term issue, per James Boyd of The Athletic. Expect Trevor Denbow and Rodney Thomas to see increased work with Indianapolis' first-team defense in Blackmon's stead.
