No schedule for Brooks' debut but mid-summer looks to be the plan. The UFC may have an opponent in mind for the debuting fighter but no word yet on who it may be. They are in the awkward position of trying to find someone a) familiar to fight fans, b) not out of Brooks' league, and c) not clearly a tomato can who fans won't recognize as a legitimate challenge.
Brooks isn't pushing his debut hard (not like he needs to pay the bills) and may not debut until much later in the year.
