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.

Kayla Harrison has a new trophy for the case. In the UFC 316 co-main event Saturday at Prudential Center, Harrison (19-1 MMA, 3-0 UFC) earned gold in emphatic fashion as she submitted Julianna Peña with a kimura at 4:55 of Round 2.

UFC fans have banded together to support Kayla Harrison after footage of her getting dominated by Ronda Rousey emerged.

UFC 316 set the foundation for some of the next title fights we'll see in the future, as Merab Dvalishvili beat Sean O'Malley to retain the men's bantamweight title and Kayla Harrison knocked off Julianna Peña to claim the women's bantamweight championship.

Both fighters put away their opponents by submission, with Dvalishvili (20-4 MMA, 13-2 UFC) tapping out Sean O'Malley in their rematch to defend his belt for a second time, while Harrison (19-1 MMA, 3-0 UFC) forced a changing of the guard with a tapout of Julianna Peña in the co-main event at Prudential Center in Newark, N.J.
