MEMORANDUM *

Michael Louis Foster, a California state prisoner, brought this suit under 42 U.S.C. § 1983, claiming that Dr. A. Enenmoh had been deliberately indifferent to his serious medical needs, in violation of the Eighth Amendment’s prohibition on cruel and unusual punishment. Foster claimed that Dr. Enenmoh knew that Metamueil was the only medicine that treated his chronic constipation effectively but refused to prescribe or approve it only because it was removed from the prison system’s formu- *610 lary. After a two-day trial, a jury returned a verdict in favor of Dr. Enenmoh. Foster appeals from the jury verdict and judgment. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

On appeal, Foster argues only that the district court abused its discretion in denying his pretrial motion for the appointment of a neutral expert witness under Federal Rule of Evidence 706. The district court’s order denying Foster’s motion was not legally erroneous, and the evidence in this case was not so complex that appointment of a neutral expert witness was required. We therefore find no abuse of discretion. See United States v. Hinkson, 585 F.3d 1247, 1268 (9th Cir. 2009) (en banc) (holding that a district court abuses its discretion if it commits legal error or if its resolution of a motion is “illogical, implausible, or without support in inferences that may be drawn from the facts in the record”); Armstrong v. Brown, 768 F.3d 975, 987 (9th Cir. 2014) (“A Rule 706 expert typically acts as an advisor to the court on complex scientific, medical, or technical matters.”); Walker v. Am. Home Shield Long Term Disability Plan, 180 F.3d 1065, 1071 (9th Cir. 1999) (finding the district court’s decision to appoint a neutral expert witness under Federal Rule of Evidence 706 “appropriate” where the court faced “confusing” and “contradictory evidence about an elusive and unknown disease”).

AFFIRMED.
