Overview
- Jurk, who fought Friday in Mannheim, flattened Edwin Castillo with a single left hook within seconds of the opening bell.
- The referee counted over a motionless Castillo and then waved the bout off as medics entered the ring.
- Video shows Castillo raising a glove toward center ring, prompting claims Jurk struck during a customary glove touch, a ritual that is not required by rule.
- The result moved Jurk to 14-0 with 12 knockouts, while Castillo fell to 13-3 with his third loss in four fights.
- Officials have not released the bout’s elapsed time, and coverage compared the quick finish to Jimmy Thunder’s 1.5-second knockout in 1997.
