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. He sent an accompanying tweet that said: “Coach just told me I have to learn a new position over the weekn,, we have IPads as playbooks now, but I’m old skool I’m using flash cards.”

The picture was eventually taken down.

He later posted a note that said, “Dear Fans: My post about learning a new position and the fact that our playbooks are now iPad was all for you.”

The team said it was aware of the situation, but declined further comment.
