Minnesota inmate Richard Johnson filed this 42 U.S.C. § 1983 action against a doctor and a physical therapist, alleging they showed deliberate indifference to his serious medical needs in treating his injured left knee. Johnson appeals the district court’s 1 adverse grant of summary judgment, and he challenges orders denying his motions to recuse and for a default judgment. Following careful review of the record and the briefs, we find no grounds for reversal, and we affirm for the reasons *140 stated by the district court. See 8th Cir. R. 47B.
