VINE: Caio Magalhaes spits blood at Josh Samman after TUF 21 beating

Is this now a thing?

On Saturday, Robbie Lawler gobbed out some blood in the direction of Rory MacDonald during his UFC title defence in Las Vegas.

It was a 'what you got?' moment and led to an intense stare-down between the two fighters.

Last night, during The Ultimate Fighter 21 finalé, Caio Magalhaes went a step further... down.

The Brazilian had just been choked out by Josh Samman and was still reeling from the loss when his opponent sought a handshake. Magalhaes' reaction was disgusting.

Once his blood stopped boiling, the BJJ expert was in more conciliatory mood.

@JoshSamman congratulation guy you was the best today. also helped me to evolve as an athlete and man required
