Pacheco (shoulder) won't practice Wednesday, Matt McMullen of the Chiefs' official site reports.
Pacheco didn't practice in any capacity last week before sitting out Sunday's 20-17 loss to the Bills. The running back remains a spectator in practice as the Chiefs begin Week 15 prep, but Pacheco will have two more chances to get in some on-field work ahead of Sunday's game against the Patriots. If the running back is unable to play through his shoulder issue this weekend, Clyde Edwards-Helaire and Jerick McKinnon would once again lead the Kansas City backfield.
