Boone (quad) is expected to be placed on IR, Mike Klis of 9News Denver reports.
Klis notes that the plan is for Boone to remain on the team's 53-man roster Tuesday, before landing on IR on Wednesday. In that context, Boone could be back in action as soon as Week 4. In the meantime, Royce Freeman is slated to handle the Broncos' No. 3 RB role behind Melvin Gordon and Javonte Williams.
