Denver Broncos rookie quarterback Drew Lock was dealt an unfortunate setback in his quest to become the team's backup behind Joe Flacco. He had appeared to be making progress in the race for the number two job, but then Lock sprained his thumb badly in the team's most recent preseason game.

He'll be sidelined for awhile, but that doesn't mean he won't be getting any work in. Per Jeff Legwold of ESPN.com, virtual reality gear will be a “significant part of his daily routine” while he recovers from the injury.

“The VR stuff upstairs is going to be heavily used … it helps a lot, being able to see what Joe does, kind of from his angle and things … being able to see every single rep, being able to see what the defense does, being able to see it in a ton of different looks,” Lock explained.

Lock apparently used virtual reality equipment during his last couple of years at Missouri, so the experience isn't entirely foreign to him. Lock is battling with journeyman Kevin Hogan to carry Flacco's clipboard to start the season.

He had been operating as the number three quarterback all offseason, but then he entered the most recent preseason game second ahead of Hogan.

It's unclear exactly how much time Lock is going to miss, but hopefully he's back before too long. Flacco is entrenched as the starter for now, but if things go south then the team will want to see what they have in their rookie sooner rather than later.
