Photos: Lubin defeats Ishe Smith by TKO; Smith announces retirement

Former world title challenger Erickson Lubin (20-1, 15 KOs) knocked down Ishe Smith (29-11, 12 KOs) a total of four times before the fight was stopped at the end of round three in a scheduled 10-round super welterweight bout. This was the first time Smith has been stopped in his career.

After the fight, Smith announced his retirement from the sport of boxing. The 40-year-old Smith won his first and only title in 2013 when he defeated Cornelius Bundradge to capture the IBF 154-pound belt — becoming the first Las Vegas-born fighter to win a major title.
