Lightweight Danny Castillo and Michael Johnson have verbally agreed to square off at the UFC 151 fight card set for Sept. 1 in Las Vegas, according to UFC officials.
The UFC announced the Castillo vs. Johnson match-up on Wednesday, and also confirmed previously reported bouts for the card pitting Dennis Siver against Eddie Yagin and Takeya Mizugaki against Jeff Hougland.
Castillo (14-4) has won his last three fights, including his May 5 bout against John Cholish at UFC on Fox 3.
Ever since losing to top UFC contender Anthony Pettis back in their WEC days, Castillo has since quietly put together a 6-1 record. His lone loss during that time was dropping a decision to Jacob Volkmann.
Johnson (11-6) made it all the way to The Ultimate Fighter 12 Finale before losing to Johnathan Brookins. He has since gone 3-1 in the Octagon, losing only to undefeated British fighter Paul Sass.
He is coming off of back-to-back victories over Tony Ferguson and Shane Roller.
UFC light heavyweight champion Jon Jones will put his belt on the line against Dan Henderson in the UFC 151 main event.
