McKinnon (groin) returned to a limited practice Thursday, Matt McMullen of the Chiefs' official site reports.
McKinnon didn't practice Wednesday, but his return to a limited session Thursday has him trending toward being available for Sunday's game against the Dolphins in Frankfurt. Fellow RB Clyde Edwards-Helaire (illness) has already been ruled out for Week 9 action, so the Chiefs could elect to elevate La'Mical Perine and/or Deneric Prince from their practice squad to provide the team with added backfield depth this weekend.
