SFAC meaning in Sports ?

The San Francisco Athletic Club was a boxing academy in San Francisco, California, known as the main training center for young boxers in the San Francisco Bay Area. The Club was opened in 1885 by Alex Greggains who had been a former middleweight boxing champion of California. Greggains was said to have formed the club because the California State Legislature had passed a law prohibiting boxing matches except before a licensed club.

The venue held a twenty-foot boxing ring called "The Bear Garden". Fighters who trained at the club included James J. Corbett, Jimmy Britt, Jack Dempsey, Joe Choynski, and brothers Abe Attell and Monte Attell. Others who fought at the venue included Bob Fitzsimmons, James J. Jeffries, and Tom Sharkey. On June 15, 1888, Australia's Peter Jackson sparred with a San Francisco deputy sheriff in an exhibition match before his American debut.
