Making good on his move to the UFC — Chidi Njokuani, the younger brother of Octagon alum, Anthony Njokuani — has his second victory under the promotion’s banner, this time stopping Serbian contender, Dusko Todorovic with a devastating first round step-in elbow knockout at UFC Vegas 55.

Njokuani, an alum of both Bellator MMA and Dana White‘s Contender Series — debuted in the Octagon back in February, stopping Marc-Andre Barriault with a series of strikes in just 16 seconds, however, this time out against Todorovic — he was almost forced to the second round.

The renowned kickboxer showed off his offensive grappling chops in the early exchanges, attempting to setup first a guillotine, and then transitioning to a D’Arce choke which ultimately failed.

After a lengthy spell at the Octagon fence in the clinch, Njokuani found some separation, and following a series of knee strikes, exploded with a massive right elbow — dropping Todorovic with just 12 seconds remaining in the opening round to land his second UFC victory.
