STATEMENT FROM SHOWTIME SPORTS:
“The women’s middleweight world championship between Claressa Shields and Christina Hammer has been postponed after Hammer withdrew from the Nov. 17 bout due to medical reasons. All parties involved have agreed to reschedule Shields vs. Hammer on SHOWTIME in 2019. In the meantime, Showtime has agreed to let Shields seek an optional title defense as Hammer pursues a return to the ring.”
