He further elaborated that, while he was training for months for a return to the UFC, he felt "physically great but something was lacking mentally". Lesnar added that "[he's] an older caveman now, so [he] makes smarter caveman decisions" and that he chose to sign with WWE instead of returning to MMA because he could "work part-time with full-time pay". Return to the UFC (2016–2018) Fight against Mark Hunt Though Lesnar said he was "closing the door on MMA" in March 2015, UFC announced on June 4, 2016, that he would return at UFC 200 on July 9.
