Flint boxing champion Claressa Shields' scheduled Nov. 17 showdown with Christina Hammer for the undisputed women’s world middleweight title is on hold due to an undisclosed medical condition that has halted Hammer's training indefinitely.
Hammer, the reigning WBC and WBO champion, confirmed that news in an Instagram post Monday evening, hours after Shields alerted her fans to the postponement on social media.
"I’m so damn mad right now," Shields wrote on Twitter. "Like I wanna punch a hole thru a brick wall."
This unification bout — the main event for a scheduled Showtime card at the Boardwalk Hall in Atlantic City, New Jersey — was announced just last week. Shields, who claimed the IBF and WBA middleweight titles in June, said she intends to fight another opponent this fall.
"We very recently were informed that Christina Hammer has a medical condition which will prevent her from participating in the bout with Claressa Shields on November 17," Shields' manager Mark Taffet said in a statement. "We were informed it is not an injury but a medical condition for which she will be treated and expects to fully recover. We are just beginning discussions with Hammer’s team, Salita Promotions, Showtime and Boardwalk Hall so we have nothing further to report at this time.
