Arkansas inmate Tyrone Ellis appeals the district court’s 1 adverse grant of summary judgment in his 42 U.S.C, § 1983 action, in which he alleged that defendant Aric Simmons was deliberately indifferent to his serious medical needs. Upon careful de novo review, see Peterson v. Kopp, 754 F.3d 594, 598 (8th Cir. 2014) (standard of review), we conclude that summary judgment was proper because, as explained by the district court, Ellis failed to show that Simmons knew of his medical complaint during the period of delay in treatment. See Fourte v. Faulkner Cty., Ark., 746 F.3d 384, 387 (8th Cir. 2014).

Accordingly, we affirm. See 8th Cir. R. 47B.
