Jairzinho Rozenstruik extended his undefeated record on Saturday, defeating Andrei Arlovski in 29 seconds on the preliminary card of UFC 244.

Rozenstruik got his win in no time, rushing his opponent with strikes. He landed a counter left hook which dropped Arlovski, giving him a walk-off victory.

The win not only continues his career-long undefeated record, but continues his UFC-long run of victories via finishing his opponent.

Rozenstruik fought once in RIZIN, defeating Andrey Kovalev at RIZIN 10. He was signed to a UFC contract after getting another win on the regional level.

The loss puts Arlovski at 1-3 1 NC in his last five outings, and 3-6 1 NC in his last 10.
