Will fifth time be a charm when Mitch Trubisky faces the Vikings?

Bears quarterback Mitch Trubisky travels through the NFL with surprise on his side: Twenty of his 29 career starts have come against teams that never had faced him.

Then there are the Vikings. Sunday will mark Trubisky’s fifth game against them, the most of any team in the league. He has faced only three other teams more than once.

The Vikings’ Mike Zimmer is one of two active coaches who have faced Trubisky more than once in the regular season. The 49ers’ Kyle Shanahan coached against him twice, and Zimmer will join the Five Timers Club on Sunday.

Does that give one side of the ball an advantage? Bears coach Matt Nagy said, perhaps wishfully, that it was probably a push.

‘‘It’s interesting to see, how do they see him?’’ Nagy said. ‘‘And how does the quarterback see the defense?’’

In a season in which each game feels like a referendum on Trubisky’s young career, watching how he fares against the team that knows him best will be another crucial data point. In Week 2, Trubisky struggled against Broncos coach and former Bears defensive coordinator Vic Fangio, the defensive coach who knew him best.

‘‘We’ve gone against this defense,’’ Trubisky said. ‘‘We know who they are as players, and they’re a very talented defense. At the same time, they know themselves and have a lot of experience playing together, as well.

‘‘So I think it kind of just goes both ways, and it comes down to execution in the game. Can we tire them down? Can we wear them down? And can we play four quarters of good, solid football?’’

The Bears have yet to do that this season, though their offensive performance Monday — in which they scored 31 points and Trubisky posted a 116.5 passer rating — was a marked improvement from the first two weeks.

But the offense still is searching for its identity. Asked whether the Bears were close to getting the offense rolling, tight end Trey Burton was blunt.

‘‘I’m not sure,’’ he said. ‘‘I would like it to be now. You never know when things are going to click.’’

The Bears plan to put Trubisky in the best position to succeed, but they also want to show the Vikings something they haven’t seen before.

‘‘You’ve just got to look at what’s worked in the past and what hasn’t and kind of just adjust and go from there,’’ Trubisky said. ‘‘And just have a couple of wrinkles that they won’t be ready for.’’

Trubisky is 2-2 in his career against the Vikings, with both victories coming last season. He made his NFL debut against them in Week 5 of 2017. In four games against them, he has thrown two touchdown passes and three interceptions, averaged 158.5 passing yards and has a 69.0 passer rating.

‘‘I guess the good thing is, it’s a lot of the same guys, so you know exactly who those guys are,’’ offensive coordinator Mark Helfrich said. ‘‘And then the bad thing is, it’s those same guys.’’

The Vikings are more diverse in their personnel packages this season, but the Bears still will see a steady diet of Vikings stars.

The defensive-minded Zimmer and coordinator George Edwards have been with the franchise for the last six years. Of the 11 starters in the Vikings’ base defense, eight have started for them for at least the last three seasons. Four can claim at least six seasons as a starter with them, including safety Harrison Smith, who is starting for the eighth consecutive season.

‘‘That alone makes you a good defense,’’ Burton said. ‘‘Add the freaks that they have on the D-line and Harrison Smith and the linebackers, it just makes them that good.’’
