Notes: V. Alexander to resume career after prison release

A few notes from around the boxing world:

• Vaughn Alexander (5-0, 4 KOs) was a tremendous prospect when he turned pro as a welterweight in 2004. Promoter Don King put him on some big cards and he fought five times in seven months. Then Alexander, the older brother of former junior welterweight and welterweight titleholder Devon Alexander, went to prison, sentenced to 18 years for armed robbery and assault of a St. Louis police officer. Vaughn Alexander, now 30, was recently released from prison early and is back in training and preparing to resume his career as a middleweight. "He's still fast and powerful," Kevin Cunningham, his trainer and manager, told ESPN.com. "I want to get him back in the ring in May. What a story this could be."

• Flyweight titlist Amnat Ruenroeng, of Thailand, will meet the Philippines' Johnriel Casimero in a rematch on May 25 in Beijing, China, on a card that will take place in conjunction with the annual IBF convention, which is in Beijing this year. Ruenroeng (17-0, 5 KOs), who will be making his sixth title defense, outpointed Casimero (21-3, 13 KOs), a former junior flyweight titleholder, to retain the 112-pound belt last June in Thailand.

• Youri Kalenga (22-2, 15 KOs), a native of Congo based in France, will fight Miami-based Cuban defector Yunier Dorticos (20-0, 19 KOs) for a vacant secondary cruiserweight title on May 20 in Paris, one day before "super" titleholder Denis Lebedev meets Victor Emilio Ramirez to unify belts in Moscow. Kalenga previously held an interim title, which he lost by unanimous decision to Lebedev last April. Kalenga, 28, won his only fight since. Dorticos, 30, has never faced a top opponent. The best name on his record is a faded Edison Miranda, who he outpointed over 10 rounds in July 2014.
