The Ultimate Fighting Championship revealed another scrap for its stacked UFC 197 card.
Roberts (12-1, 1-0 UFC) impressed in his Octagon debut with a first-round submission of Nathan Coy. The Next Generation UK product is a proven finisher, having submitted or knocked out 10 of his 13 professional opponents.
Steele (14-6, 1-1 UFC) is also a potent finisher, as he proved with a vicious knockout slam of Dong Hyun Kim last November. The 28-year-old Cincinnati native has won three of his last four bouts.
