The 49ers’ defense has allowed 20-plus points in three consecutive games for the first time all season. It won’t get any easier with Aaron Rodgers and the Green Bay Packers coming to town for their highly-anticipated Sunday night matchup. The defense will need to click in all facets of the game to stop Packers head coach Matt LaFleur’s offense.

Here are the six players that will be key in doing just that:

CB Richard Sherman

Sherman was called for pass interference three times last week against the Cardinals. Sunday night he’ll be tasked in coverage plenty against wide receiver Davante Adams, who leads the Packers in targets despite missing four games. Sherman will need to be careful in coverage because the last thing the defense wants to do is give Rodgers free yards. Pass interference penalties against the Packers are especially damaging because Rodgers isn’t afraid to take deep shots.
