Mexican boxer Jeanette Zacarias Zapata has died after succumbing to injuries she sustained in a bout against Terrebonne’s Marie-Pier Houle last Saturday in Montreal.

Zapata, 18, was rushed to a Montreal hospital after being knocked out by Houle at IGA Stadium. The fight was stopped at the end of the fourth round. Zapata died on Thursday, the event’s promoter Groupe Yvon Michel confirmed in a statement posted to Instagram.

“It is with great sadness and torment that we learned, from a representative of her family, that Jeanette Zacarias Zapata passed away this afternoon at 3:45 p.m. The entire team at Groupe Yvon Michel is extremely distressed by this painful announcement,” Michel shared on Twitter.

During the bout, Zapata reportedly began convulsing, and was subsequently taken to the hospital, where doctors placed the boxer in a medically-induced coma. She reportedly died with her husband, Jovanni Martinez, by her side.

Following news of her opponent’s death, Houle, according to The Sun, took to social media to extend her condolences to Zapata’s family.

“Thank you for respecting my desire not to comment more,” her opponent said. “The sad news of the departure of a great athlete like Jeanette Zacarias Zapata leaves me sad and devastated. I offer my sincere and deep condolences to her family and husband Jovanni Martinez. May God enlighten your soul and receive it in his glory.”

The World Boxing Council also released a statement.

“The president of the WBC, Mauricio Sulaimán and the entire boxing family affiliated with the WBC, as well as all boxing, mourns this irreparable loss. We send our deepest condolences to the family and friends of Jeanette. May she rest in peace.”

Zapata’s fight against Houle was her sixth as a professional boxer.
