McIntosh didn't play on offense in Sunday's 26-20 win over the Broncos.
No. 1 running back Kenneth Walker left in the fourth quarter with an abdominal injury, and Zach Charbonnet carried the entire backfield workload the rest of the game. Walker's status for the Week 2 matchup versus the Patriots is in flux as a result, and if he misses time, McIntosh should line up as the clear No. 2 back behind Charbonnet.
