The former boxing champion struggled to implement her game plan on Silva, however. Holm worked Silva to the fence early in the fight and looked to set up short knees and punches to the body, but Silva seemed unbothered by the offense. Once Silva broke free of Holm's grip, Silva was clearly the more
