ENGLEWOOD, Colo. — A person familiar with the situation says Broncos rookie quarterback Drew Lock will miss the rest of the preseason because of a sprained right thumb.
The team hasn’t officially revealed the severity of the injury. Lock is competing with Kevin Hogan to be Joe Flacco’s backup.
Lock was hurt early in the third quarter of Monday night’s preseason loss to San Francisco.
The second-round pick out of Missouri was tripped up trying to leave the pocket and landed on his thumb as he attempted to pitch the ball to a receiver.
Lock won’t need surgery.
The Broncos have two preseason games remaining before the season opener Sept. 9 at Oakland.
