Pacheco (knee) won't practice Thursday, Matt McMullen of the Chiefs' official site reports.
With consecutive DNPs on Wednesday and Thursday due to an MCL sprain in his right knee, Pacheco is trending in the wrong direction ahead of Sunday's game against the Bills, and it's possible that he'll be ruled out as soon as Friday. If Pacheco is unavailable this weekend, Kareem Hunt would be in line for more carries Week 9, per ESPN.com, with Brashard Smith and Elijah Mitchell backing him up.
