Ryan Koerdt appeals the district court’s 1 adverse grant of summary judgment in his employment-discrimination action. Having considered the briefs and the record in light of the standard of review set forth in Jain v. CVS Pharmacy, Inc., 779 F.3d 753, 759 (8th Cir. 2015), we conclude that no extended discussion is necessary, and thus we affirm on the basis of the district court’s opinion. See 8th Cir. R. 47B.
