1) Mauricio Rua

Possibly one of the greatest fighters in the history of the sport, Mauricio Shogun Rua, is a former Light Heavyweight Champion in the UFC.

However, age might be catching up to him as the 39-year-old lost his last fight to Paul Craig. The Brazilian can still do a decent job but the Heavyweight division is loaded with several big names, especially with Jon Jones moving up.

Silva was an example of a big name leaving and Rua could be part of the UFC roster cuts too.
