The Kayla Harrison era has arrived. The two-time Olympic gold medalist finally captured UFC gold at UFC 316 with a submission win over Julianna Peña in the second round of Saturday's co-main event.

The two-time bantamweight champion had spent months going after two-time Olympic gold medalist Harrison any way possible prior to their UFC 316 co-main event. Their back-and-forth has been unusually heated for a women’s fight, and led to a tense feeling in the Prudential Center.

UFC women's bantamweight titleholder Julianna Peña asked Kayla Harrison during a press conference how she plans to defeat her at UFC 316, which takes place on June 8 in Newark, Newark, USA.
