Bobby Green made it known he would step in on short notice and face Al Iaquinta if the UFC wanted to make the bout. Instead, he will get Danny Castillo at UFC on FOX 8.
Officials confirmed the bout on Thursday. The two lightweights are likely slated for the prelims on July 27 from the KeyArena in Seattle.
Green (20-5) earned a win in his Octagon debut earlier this year, stopping Jacob Volkmann via submission. He has won five straight fights overall.
Castillo (15-5) sports a 5-2 UFC record, including a recent win over Paul Sass. He is 4-1 in his last five fights.
