Michael J. ANDRASON, Appellant,
v.
SHERIFF, WASHOE COUNTY, Nevada, Respondent.
No. 7003.
Supreme Court of Nevada.
November 16, 1972.
LeRoy Arrascada, Reno, for appellant.
Robert List, Atty. Gen., Carson City, Robert E. Rose, Dist. Atty., and Kathleen *16 M. Wall, Deputy Dist. Atty., Reno, for respondent.

OPINION
THOMPSON, Justice:
The appellant, Andrason, was charged with having committed the crime of battery with resulting "serious physical injury" to the victim, a gross misdemeanor.[1] Following a preliminary examination he was held to answer in the district court. In that court he filed a pretrial petition for a writ of habeas corpus in which he challenged the sufficiency of the evidence to bind over and the constitutionality of the statute under which he was charged. This appeal is from the order of the district court denying habeas relief. He contends that the evidence produced at the preliminary examination fails to show that the battery he committed resulted in "serious physical injury" to his victim. Moreover, he argues that the phrase "serious physical injury" is unconstitutionally vague. Neither contention has merit.
1. The victim, a middle-aged female, was kicked in the groin and lost consciousness as the result of the pain therefrom. The area turned black and blue, was swollen, and a lump developed. Four months after the incident her legs still bothered her after standing any length of time. She was treated by two doctors for her injury. This evidence supports a reasonable inference that the victim sustained a "serious physical injury," and satisfies the quantum of proof necessary to allow the magistrate to order that the accused be held for trial in the district court. Graves v. Sheriff, 88 Nev. 436, 498 P.2d 1324 (1972); Kinsey v. Sheriff, 87 Nev. 361, 487 P.2d 340 (1971).
2. The words "serious physical injury" are words of ordinary significance and readily understood by men of ordinary intelligence. State v. McKeehan, 91 Idaho 808, 430 P.2d 886 (1967); State v. Perry, 5 Ariz. App. 315, 426 P.2d 415 (1967); Thomas v. State, 55 Tex.Cr.R. 293, 116 S.W. 600 (1909). Accordingly, the statutory language accommodates constitutional commands. Parkus v. State, 88 Nev. ___, 501 P.2d 1039 (1972).
Affirmed.
ZENOFF, C.J., and BATJER, MOWBRAY, and GUNDERSON, JJ., concur.
