McKenzie is listed as the No. 3 receiver on the Colts' first unofficial depth chart of the preseason, Raven Moore of the team's official site reports.
He's notably listed ahead of rookie Josh Downs, his primary competition for the slot role, though McKenzie getting the No. 3 designation may be in deference to his veteran status. Given the third-round draft capital the Colts invested into him, Downs may still be the frontrunner to win the slot job, but McKenzie could still craft out a meaningful rule even as Indianapolis' No. 4 receiver and punt returner.
