UFC Vegas 23 medical suspensions: Mackenzie Dern, five others facing six-month suspensions

Mackenzie Dern may have to wait to capitalize on the biggest win of her UFC career.

The jiu-jitsu specialist picked up one of the most impressive victories at Saturday’s UFC Vegas 23 event, finishing Nina Ansaroff with a slick armbar submission in the first round of their main card bout. Dern’s finish earned her a $50,000 Performance of the Night bonus, but she’s also facing a potentially lengthy injury suspension.

According to the list of medical suspensions released Tuesday by mixedmartialarts.com, Dern requires an X-ray on her right thumb.
