The UFC is making good on its promise to make Kelvin Gastelum move up to middleweight.
The top prospect will go back to his former division and meet Nate Marquardt at UFC 188 on June 13 in Mexico City, the UFC announced Tuesday.
Gastelum won The Ultimate Fighter 17 reality series at middleweight in 2013, but moved down to welterweight afterward. He struggled to make the 171-pound maximum there and was told to move up after missing weight by nine pounds before his bout with Tyron Woodley at UFC 183 on Jan. 31 in Las Vegas.
