Let's remind that after loss by a knockout to Alastair Overim in December, 2011 in main event UFC 141 Brock directly in an octagon made the statement for the resignation.

"I miss, but I shouldn't follow the tastes of feelings. In recent years I was traumatized much therefore I couldn't act as I would like. I too quickly returned. But if ifs and ans were pots and pans. I turned that page of the life and opened the new. Now I feel in a full order. I really never thought of making something in a different way, to make as it was necessary. I am not that guy that was earlier. Now everything suits me. There are days when I think of return in октагон to become that whom I was earlier. But I don't intend to come back to it".
