The first part also applies to fighters in Bellator, Strikeforce, M1, etc. on a regular basis. However, the majority of a fighter's income is not from base salary, but via sponsors. For example: fight shorts, hats, walkout gear (t-shrits, sweats, etc). As an example, if you look at Thiago Alves e Koscheck's trunks, they are covered with sponsors, from which they get paid.
