Song Yadong knocked out Umar Nurmagomedov in the bantamweight main event at UFC Fight Night in Shanghai. The upset was stunning because Nurmagomedov entered as the heavy favorite. Song's knockout puts the Chinese fighter into legitimate title contention and ends what looked like a coronation fight for the heavily backed Russian prospect.
Nurmagomedov came in undefeated and was widely expected to cruise through this matchup on his way up the rankings. Instead, Song caught him and finished it decisively. This is the kind of result that reshuffles the 135-pound pecking order and gives Song legitimate claim to next-level opponents. The bantamweight division just got more unpredictable.
