After the game, which Broncos fell 26-21, Lock spoke to journalists with his arm in a sling. He says he's optimistic.

"(He) Said it didn't feel normal when he tried to throw on the sideline," CBS4's Michael Spencer posted on social media.

ESPN reports Lock will be out for at least two weeks, but up to six weeks. An MRI scheduled for Monday is suspected to give the team a better idea of that timeline.
