Buffalo head coach Sean McDermott said Tuesday that he expects McKenzie (shoulder) to be a "full go" for Sunday's season opener versus Pittsburgh, Chris Brown of the Bills' official site reports.

With that in mind, McKenzie looks on track to turn in three full practices Wednesday through Friday, which should erase any concerns about the health of the shoulder he injured in an Aug. 24 workout. McKenzie is expected to fill a depth role in Buffalo's wideout corps while also serving as the team's top option in the return game.
