Unbeaten junior middleweight Alexander Abraham (25-0-1, 17 KOs), the younger brother of boxing superstar Arthur Abraham, has retired from the ring. According to trainer Ulli Wegner, an unexplained dizziness prompted the 28-year-old prospect to hand up his gloves. Meanwhile Arthur Abraham is headed to the United States to face Andre Dirrell in SHOWTIME’s acclaimed Super Six tournament on March 6 in Palm Springs, CA.
