GREEN BAY – The Buffalo Bills come into Lambeau Field fresh off their unexpected dominance of the Vikings in Minnesota last week.

Here's what to watch:

1. Key perimeter matchup: Packers WR Davante Adams is regularly drawing the opponent's top cover corner, and this week that's Bills CB Tre'Davious White. As a rookie first-round pick last year out of LSU, White intercepted four passes. Adams leads the Packers with 20 receptions and three touchdowns, and he's just behind Geronimo Allison in receiving yards (209 to 204). For all the sentiment around S Micah Hyde's return to Green Bay to face his old team, Adams vs. White is the matchup in the Buffalo secondary to watch.

2. Pass rushers: The Bills took control early against the Vikings with their pass rush, as DEs Jerry Hughes and Trent Murphy each recorded a strip sack of Minnesota QB Kirk Cousins. Through three games, the Packers have just six sacks as a team, and with LB Nick Perry in the concussion protocol and DL Muhammad Wilkerson out, more snaps are likely for players like LB Reggie Gilbert and DL Dean Lowry. They'll be counted on for more impact.

3. Toughing it out: Bills RB LeSean McCoy has insisted this week he'll play despite injured ribs. He's been limited to 16 carries for 61 yards so far in 2018, but he's an explosive player who also can help rookie QB Josh Allen in the passing game. If McCoy plays, Buffalo's offense takes on a different dimension.

4. Reaching full speed: The Packers have their own ball-carrier getting back in the swing of things in RB Aaron Jones, who returned from a two-game suspension last week. He busted off runs of 8, 10 and 17 yards at Washington, but carried the ball just three other times in a limited role. That role could begin expanding.

5. Back on the climb: At 1-1-1, the Packers will look to get back above .500 at the quarter pole of the regular season. The last time Green Bay was under .500 through four regular-season games was way back in Head Coach Mike McCarthy's first season, in 2006.
