According to multiple reports, including a post by Dethrone Royalty on Twitter, the UFC will make an announcement on Tuesday to confirm Reebok as the official sponsor for the promotion.
Heard uniform announcement coming tomorrow. We were never about all looking the same. We'll stay that way, thanks. #goodluckreebok

Rumors of a sponsorship deal have been consistent for over a year, as UFC president Dana White has stated numerous times they have been working on something. During a recent press conference to announce the 2015 schedule, an expected-announcement was delayed.
If the reports are true, fighters would not be allowed to wear other sponsors inside the Octagon.
