The preseason football game between the Arizona Cardinals and the Oakland Raiders on Friday night was marred by a frightening act of violence. A man was shot in the face not far from University of Phoenix Stadium, according to ABC 15 in Glendale and various other reports.

The Arizona Republic reports that the shooting occurred during an altercation in a parking lot near the stadium during the third quarter of the preseason contest won by the Cardinals, 31-27.

According to the Contra Costa Times, the police were called by the suspected shooter, who claims the incident was an accident. Shortly after the shooting, KTLA TV reported that the 30-year-old gunshot victim was facing life-threatening injuries and the suspected shooter was in police custody.

Glendale police officer Tracey Breeden would later say that the man who was shot was in stable condition, per the Mercury News.

Unfortunately, there is ample precedent for such violence amongst fans, even at preseason NFL games. Last year, two men were shot and wounded outside of a preseason game at Candlestick Park between the Raiders and the San Francisco 49ers.
