Watch the UFC 183 Weigh-Ins Live Featuring Anderson Silva and Nick Diaz

Former middleweight champion Anderson Silva will make his long-awaited return to the Octagon this Saturday night at UFC 183 in Las Vegas. His opponent will be the inscrutable Nick Diaz, who is also returning to action after being away for over a year. 

Silva's layoff was the result of a gruesome leg injury. Meanwhile, Diaz took time off because he'd grown tired of fighting. It was only a fight and big payoff opposite Silva that brought him back. 

Before their fight can be made official, both fighters have to make weight. There will be 22 fighters in total weighing in Friday at 7 p.m. ET. 

Thursday, the two faced off during the UFC 183 media day—and things ended with a hug. The two have been very respectful with each other in the lead-up to this fight, the polar opposite of what we saw with Jon Jones and Daniel Cormier in the buildup to their fight earlier this month. 

While nobody knows exactly how this fight will play out, most seem to be picking the 40-year-old former champ in Silva. Diaz is moving up in weight to face a bigger, stronger opponent. While both are great strikers, Silva is much more diverse, and his incredibly accurate counter-striking approach is tailor made to take out the hard-charging, overaggressive approach of Diaz. 

But it's an MMA fight and anything can happen once those cage doors close.
