Oliveira (30-8, 1 NC) has won eight straight fights, most recently a dominant decision over Tony Ferguson in December. The 31-year-old Brazilian is No. 3 in the ESPN lightweight rankings.
The fourth-ranked Chandler (22-5) is a three-time Bellator lightweight champion. He made his UFC debut in January, knocking out Dan Hooker in the first round for his third straight win.
In the co-main event, also a matchup of top-10 lightweights, Ferguson will try to break out of a two-fight losing streak -- which followed 12 wins in a row -- when he faces Beneil Dariush. Ferguson is ranked fifth and Dariush eighth.
