Brown has a New Edition show set for 8pm at the Mohegan Sun Indian Casino in Connecticut, TMZ reports.
The gig would be just hours after ex-wife Houston's funeral, which takes place at noon that day, and will feature speakers including The Bodyguard co-star Kevin Costner and mentor Clive Davis.
A private viewing of Houston's body for family and friends has also been scheduled for Friday, February 17.
Bobby Brown and Whitney Houston split in 2007 after 15 years of marriage, during which time they both struggled with drug abuse.
Brown performed with New Edition on the night of Houston's death. During the set, he expressed his feelings for Houston when he broke down crying and said: "Whitney, I love you."
