McKinnon (groin) won't practice Wednesday, Matt McMullen of the Chiefs' official site reports.
McKinnon sat out practice last Thursday with the same injury before practicing fully Friday and playing 23 snaps on offense in the Chiefs' Week 8 loss to the Broncos. The Chiefs haven't disclosed whether McKinnon's absence Wednesday is the result of a setback or a matter of load management, but more information on the running back's status should arrive Thursday. If McKinnon is available Sunday against the Dolphins, he'll continue to work in a change-of-pace role behind Isiah Pacheco.
