ENGLEWOOD, Colo. (AP) – Denver Broncos linebacker D.J. Williams appeared to reveal defensive formations when he sent out a picture of his digital playbook on his Twitter account.

The Broncos gave the players iPads this offseason as an alternative to more customary playbooks and Williams posted a picture on his account.
