UFC 276: Brad Riddell submitted in first minute of lightweight bout with Jalin Turner

Kiwi UFC lightweight Brad Riddell has fallen to a hasty first-round submission defeat to rising star Jalin Turner at UFC 276 in Las Vegas on Sunday (NZ time).

Fighting in the feature bout of the preliminary card, 'Quake' barely had a chance to find his rhythm against Turner, who immediately put his significant height and reach advantage to use.

The American tagged the City Kickboxing product with a lightning straight right-hand, then caught him as he attempted to grapple his way to safety and immediately locked in a guillotine choke.

Riddell tried to defend but Turner's mounted position proved too much to contend with and he was forced to tap just 45 seconds into the contest, further stamping the 'Tarantula' as one of the lightweight division's most promising prospects.

The tallest fighter in the class at 6ft 3in, the finish was Turner's fifth straight, dating back to his win over Australian Josh Culibao at Auckland back in February 2019.

The loss is Riddell's second straight, after he began his UFC tenure with four consecutive victories. He was knocked out in the third round of his fight with Rafael Fiziev in December.

The 30-year-old former world champion kickboxer entered Sunday's bout as the 14th-ranked lightweight.
