A late addition to UFC on ESPN 43 will no longer take place.

The promotion officially announced Thursday evening that Tamires Vidal is out of her scheduled bout against Hailey Cowan due to an undisclosed medical issue. The event taking place at AT&T Center in San Antonio will proceed with 12 bouts, as there will be no replacement for Cowan (7-2 MMA, 0-0 UFC).

Earlier this month, MMA Junkie first reported the booking, which was the final matchup to complete the card. The event airs on ESPN at 7 p.m. ET following prelims on ESPN+, beginning at 4 p.m. ET.

Vidal (7-1 MMA, 1-0 UFC) made her UFC debut in November, where she finished Ramona Pascual with a flying knee in the first round at UFC Fight Night 214.

Cowan, who was signed to the UFC from Dana White’s Contender Series, attempted to make her debut in February, but it fell through due to medical issues of her own. An ovarian cyst rupture forced the 31-year-old fighter to withdraw from the bout, leading to the booking against Vidal. Now, her debut will have to wait even longer.

The updated UFC on ESPN 43 lineup is as follows:

• Marlon Vera vs. Cory Sandhagen
• Holly Holm vs. Yana Santos
• Nate Landwehr vs. Austin Lingo
• Maycee Barber vs. Andrea Lee
• Manel Kape vs. Alex Perez
• Albert Duraev vs. Chidi Njokuani
• Tucker Lutz vs. Daniel Pineda
• Lucas Alexander vs. Steven Peterson
• Trevin Giles vs. Preston Parsons
• Daniel Da Silva vs. CJ Vergara
• Trey Ogden vs. Manuel Torres
• Victor Altamirano vs. Vinicius Salvador
