UFC 278 pre-event facts: Why Kamaru Usman vs. Leon Edwards rematch is a first

The UFC’s eighth numbered event of the year takes place Saturday with UFC 278, which takes place at Vivint Arena in Salt Lake City and airs on pay-per-view following prelims on ESPN/ABC and early prelims on ESPN+.

An unprecedented matchup takes place in the main event, with two fighters carrying UFC unbeaten streaks of 10 fights or more against each other for the first time.

Reigning welterweight champion Kamaru Usman (20-1 MMA, 15-0 UFC) will look to add to his 15-fight winning streak and match Anderson Silva’s record for most consecutive fights in the promotion without a loss, while Leon Edwards (18-3 MMA, 10-2 UFC) brings a 10-fight unbeaten streak into his first title opportunity.

The last time they met, Usman won a unanimous decision at UFC on FOX 17 in December 2015, but Edwards hasn’t lost since.
