Boone is expected to serve as the Broncos' No. 2 running back behind Javonte Williams in Sunday's game against the Chiefs with Melvin Gordon (hip/shoulder) listed as doubtful for the contest, Kyle Newman of The Denver Post reports.
Gordon wasn't able to practice in any capacity this week, making it likely that he'll be inactive for the first time all season. Through their first 11 games, the Broncos have deployed a near-even backfield timeshare of Gordon and Williams, with both receiving similar snap and touch counts in nearly every game. That has left scant work for Boone since coming off injured reserve Week 6, though he showed the ability to produce on the occasions he saw carries for the Vikings the past three seasons. Even so, rather than simply plugging Boone in for Gordon as part of a timeshare, the Broncos are more likely to prepare the Williams for his first look in a three-down bellcow role, with Boone likely mixing in when the rookie requires a breather.
