The Minnesota Vikings are still unscathed a month into the NFL season, as an elite defense has led Kevin O'Connell's group to a 4-0 start. On Sunday, they will try to keep that unbeaten record on the road against the New Orleans Saints.

While the defense has been clicking on all cylinders so far this season, the Vikings have had to deal with a number of key injuries on offense. Justin Jefferson missed Week 4 with an ankle injury, while Jordan Addison is dealing with a hamstring injury heading into this one.
