UFC officials made the announcement on Thursday.
Barao and Wineland were originally scheduled to fight at UFC 161 on June 15, but a foot injury forced Barao out of the fight.
With the interim bantamweight title bout rescheduled, UFC 165 now features two title bouts.
Barao (30-1, 1 no contest) won the interim title by defeating Urijah Faber at UFC 149 on July 21, 2012. The 26-year-old Brazilian hasn’t lost since 2005 and is on a 30-fight winning streak.
Wineland (20-8-1) earned his title shot by defeating Brad Pickett at UFC 155 on Dec. 29.
Bantamweight champion Dominick Cruz has been out of action since October 2011 with a knee injury. He’s undergone two surgeries to correct a torn anterior cruciate ligament (ACL) and is expected to return later this year.
