The 145-pound bout adds to the developing card, which takes place on Jan. 31 at a yet-to-be-announced venue.
Brandao (18-10) is coming off of two straight losses for the first time since making his UFC debut. In his last outing, the Brazilian fighter met Conor McGregor in the main event at a UFC Fight Night last July. The bout ended shortly after it started with McGregor picking up a technical knockout in the first round.
After making an impressive debut in 2011, Hettes (11-2) has lost two of his last three. In his most recent fight, “The Kid” met Dennis Bermudez and suffered a TKO to the top-ranked featherweight.
