Minnesota inmate Todd Myers appeals the district court’s 1 grant of summary judgment dismissing his 42 U.S.C. § 1983 claims against the Anoka County Sheriff, Detention Deputy Andrew Schroeder, and unnamed Nursing Staff and “Dr. on Call” defendants for causing the delayed medical treatment of a broken jaw Myers suffered during an assault by another inmate at the Anoka County Jail.

After careful de novo review of the record, we conclude that the district court (i) did not abuse its discretion by dismissing Myers’s claims against the unnamed medical staff defendants because he failed to identify and serve those defendants for more than a year after filing this action, see Fed.R.Civ.P. 4(m); (ii) properly granted summary judgment in favor of Deputy Schroeder because, even crediting Myers’s disputed testimony that he told Schroeder immediately after the assault that he needed to see a doctor or nurse because his jaw and face hurt, Myers admitted that he complained of pain in his jaw to a nurse “at the next Med line” and received some medical attention, so any failure by Schroeder to seek medical attention for Myers was not the cause of any delay in providing the necessary treatment; and (iii) properly dismissed the official capacity claims because Myers failed to identify any Anoka County policy that violated his constitutional rights. Nor did the district court abuse its discretion in denying Myers’s request for the appointment of counsel. See Phillips v. Jasper County Jail, 437 F.3d 791, 794 (8th Cir. 2006).

The judgment of the district court is affirmed. See 8th Cir. R. 47B.
