Denver Broncos CB: I've Been Hacked, Too ... Just Like Tunsil

Another NFL star says his social media account has been HACKED -- with Denver Broncos cornerback Chris Harris Jr. saying someone infiltrated his Instagram to post a potentially damaging photo.

Harris -- a 2-time Pro Bowler and Super Bowl champ -- went to Twitter and wrote, "Someone hacking IGs someone just tried me smh."

We didn't see the photo ourselves -- but we're told the pic appeared to show Harris smoking a rolled cigarette.

Unclear if there's a connection between the Harris hack and the Laremy Tunsil incident.
