Quarterback Ian Book, a former fourth-round draft pick of Sean Payton’s, is attending Denver’s rookie minicamp as a veteran tryout player.

With Desmond Ridder backing out of his tryout at Broncos rookie minicamp, the club is bringing in a quarterback who has been with head coach Sean Payton before.

The Denver Broncos made a quarterback decision ahead of rookie minicamp after Desmond Ridder backed out, paving the way for Ian Book to reunite with Sean Payton.
