The San Antonio Spurs are a professional basketball team based in San Antonio that competes in the National Basketball Association (NBA). In 1967, the franchise was founded in Dallas, Texas as the Dallas Chaparrals--one of the eleven charter franchises of the American Basketball Association (ABA). During the 1970–71 season, in an attempt to make the team a regional one, the franchise renamed itself the Texas Chaparrals; also, some home games were played in Fort Worth and Lubbock. However, low attendance figures prompted the team to return full-time to Dallas the following season. In 1973, the franchise relocated to San Antonio and was renamed the San Antonio Spurs. Three years later, the Spurs were one of four ABA franchises that joined the NBA as a result of the ABA–NBA merger.
