Missouri inmate Jack L. Jackson appeals the district court’s 1 adverse grant of *669 summary judgment in his 42 U.S.C. § 1983 action against a nurse and a doctor. Because the summary judgment record confirms that defendants did not know of and disregard Mr. Jackson’s serious medical need, his deliberate-indifference claims fail. See Miller v. Schoenen, 75 F.3d 1305, 1309 (8th Cir. 1996) (to establish deliberate indifference, inmate must show both that he had objectively serious medical need and that defendants knew of and disregarded that need). Further, “[a]n inmate’s failure to place verifying medical evidence in the record to establish the detrimental effect of delay in medical treatment precludes a claim of deliberate indifference to medical needs.” Coleman v. Rahija, 114 F.3d 778, 784 (8th Cir. 1997). Accordingly, we affirm the judgment of the district court. See 8th Cir. R. 47B.

We also deny Mr. Jackson’s motion for appointment of counsel.
