When referee Sam Burgos stepped in during the BKFC 62 co-main event, he ended the fight – but inadvertently started another. Seemingly dazed from a series of punches that led to a first-round TKO stoppage, Keith Richardson (4-1) didn’t pick up on the fight being over nor who was his intended target Saturday at Seminole Hard Rock Hotel & Casino in Hollywood, Fla. After Burgos entered the pocket to halt the action, Richardson continued to throw, only the referee was the one he aimed at instead of opponent Alberto Blas (6-0)
