Before the start of the 2016 season, the Panthers announced increased security changes.

There are now metal detectors and walk-through scanners, and surveillance has been doubled.

The team said earlier this week that they’ve been in contact with government officials and the Charlotte-Mecklenburg Police Department to prepare for Sunday’s game.

This week, CMPD Chief Kerr Putney said that he's confident the department has the resources to keep the city safe.

Fans should also expect to see highly trained bomb-sniffing dogs around Bank of America stadium Sunday afternoon when the Panthers take on the Minnesota Vikings.

Panther’s fans said they aren’t overly concerned about game security.

“[I’m] a little nervous, but not too worried," one fan said. "I know they got a handle on things pretty well down here. There’s a lot of police and stuff uptown. You see the guys in uniform. I think it'll go pretty smoothly tomorrow."

A spokesman said the National Guard is still expected to be in Charlotte on Sunday, but could not say whether guardsmen would be on hand at Bank of America Stadium for the game.
