McKenzie (undisclosed) will return to practice Sunday, Jay Skurski of The Buffalo News reports.
Coach Sean McDermott says his slot receiver has been "nicked up," so while he's not out of the woods yet, this bodes well for his chances of playing in Thursday's season-opening game against the Rams. When healthy, McKenzie is expected to be the team's top slot receiver, though Jamison Crowder is also likely to have some role in the offense.
