Report: Broncos' Drew Lock signs rookie deal

Drew Lock has agreed to terms with the Denver Broncos, sources told Pro Football Talk's Mike Florio.

The second-round pick and presumed Broncos quarterback of the future has reportedly signed a day before the team's first rookie training camp practice. He's the last Denver Broncos rookie to sign his entry-level contract.

Lock's representatives were negotiating a rookie deal that accounts for him potentially becoming Denver's starting quarterback over his first four seasons, according to ESPN's Jeff Legwold.

Asked Wednesday morning if he thought the two sides could reach a deal before Thursday's practice, Broncos GM John Elway didn't say much.

"We'll see," he said. "I'm not going to make a prediction one way or the other."
