-- T.J. Grant released a statement (via Twitter) with an explanation on exactly why he was forced out of the UFC 164 main event against Benson Henderson. Grant says he suffered a concussion in Brazilian jiu-jitsu training and did not have enough recovery time to be completely healthy for the Aug. 31, 2013 bout in Milwaukee, Wisconsin. The Canadian’s misfortune is Anthony Pettis’ gain as “Showtime” will step in to face Henderson in a highly anticipated rematch from WEC 53 in 2010.
