As the UFC returned to Abu Dhabi, Roy Nelson made sure that the fans got their moneys worth with a crushing first round victory over heavyweight legend, Antonio Nogueira.

Known as one of the best 'one-punch KO' in UFC history, Nelson made short work of the MMA legend in brutal fashion.

After rocking Nogueira twice with big hits, Nelson delivered the third and final blow. A huge right hook left Nogueira lying flat on the mat and unconscious as Nelson simply walked away.

It was perhaps the final swansong for Nogueira, who's MMA record stands at 34-9-1 and 1 NC after the fight. The 37 year old was a pioneer of the sport and is highly respected throughout the MMA community.

Nelson even paused his post-fight interview to praise him saying "he's the reason we're here today."

Yet it's been rocky couple of years for 'Big Nog' and he's 3-5 in his last eight fights. This was the first time he's ever lost two fights in a row.

It would be a disappointing end to a historic career but at the same time he's been a shadow of his former self for a while now.

In his post-fight interview Nelson stated that all he wants to do is fight for a title and will fight anyone to get to that point. Yet at 37 years of age and this being the biggest win of his career, it's unlikely he'll get that opportunity without a big win later this year.

For the UFC It was certainly a more impressive showing in the UAE second time round. They previously came to the Middle East in 2011 but with Anderson Silva seemingly clowning around in his fight against Demain Maia, Dana White and the crowd were far from pleased.

Another big factor in the happy crowd had to be the Featherweight bout between Japan's Tatsuya Kawajiri and the American, Clay Guida.

Kawajiri came into the fight on a six fight win streak, while Guida was 1-3 in his last four fights.

Guida is known for his ability to put on a show inside the ring and he did a fantastic job of livening up the crowd with a dominant performance.

He showcased every major aspect with near knockout punches, great submission attempts and escapes, as well as performing a series of brutal slams on his opponent over the course of the fight.

With a unanimous decision victory, Guida called out White for 'protecting' Ireland's Conor McGregor and stated that he "wants to fight that little leprechaun".

He wasn't the first to call-out McGregor on the night either. Jim Alers laid down the challenge after he beat Alan Omer via split decision on the prelims.

Despite being known for his trash-talk, McGregor stayed calm, tweeting only "Everybody wants it. Until they get it." He's been tipped for UFC Dublin in three months time so expect things to heat up before then.
