In his new sport, he became a two-time All-American defensive lineman, playing on a team that lost only two games, en route to winning the black college football national championships in 1971 and 1973.He became a starter at left defensive end during his second season in 1975, and in 1977 he helped the Cowboys win Super Bowl XII.A former Golden Gloves fighter in Tennessee, Jones fought six professional bouts as a heavyweight, with a perfect 6–0 record and five knockouts.Jones survived the round and was awarded a narrow majority decision, causing the pro-Meneses crowd to boo loudly.But his other five opponents were journeymen at best, with the arguable exception of Mexican heavyweight champ Fernando Montes, whom Jones knocked out in just 44 seconds on November 24, 1979.[11] Jones returned to play for the 1980 season, replacing John Dutton at defensive end and performing better than his first stint with the team.In the fifteenth game, he batted a pass into the hands of teammate Jim Jeffcoat, whose 65-yard touchdown return changed the momentum in the 28–21 win for the NFC East title.The NFL did not start recognizing quarterback sacks as an official stat until 1982; although the Cowboys have their own records, dating back before the 1982 season.
