The Wizards-Celtics rivalry is … HEATING UP!

Tim Kitzrow, whose voice provided the soundtrack for the popular video game “NBA Jam,” will serve as the guest public address announcer on Tuesday at Verizon Center, where the Wizards will “celebrate the ’90s” as part of a Throwback Night promotion and go for their 14th consecutive win at home by burying the hated Celtics, so to speak.

After Monday’s 109-99 win over the Hornets in Charlotte, Wizards players announced that they would arrive at the arena for Tuesday’s game dressed for a funeral.

“We’re wearing all black to the game,” Kelly Oubre Jr. said. “So you know where we’re going with that. … We’re ready for whatever, man. Round three. Let’s get it.”

“All black everything,” John Wall said. “A funeral.”

The funeral attire was apparently Bradley Beal’s idea. The Celtics were not impressed.

“That’s cute that they’re wearing all black,” Celtics guard Isaiah Thomas said Tuesday, via CSN’s Chase Hughes. “I just kind of laughed [when I heard]… it’s not like it’s a Game 7.”

For the game, the Wizards will wear their red “Baltimore Pride” uniforms, which pay homage to a Baltimore Bullets team that never played in the ’90s. Decade-appropriate Washington Bullets alumni scheduled to attend the game include Mark Alarie, Tom Hammonds and Gheorghe Muresan, while the hip-hop duo “Tag Team,” best only known for their 1993 hit “Whoomp! (There It Is),” will perform at halftime.

The Wizards and Celtics, whose beef has been brewing since last year, split their first two meetings this season, with each team winning on its home court. After the Celtics’ victory over the Wizards at TD Garden earlier this month, Boston forward Jae Crowder and Wall exchanged words on the court and Crowder put his index finger on Wall’s nose. The shouting continued in the hallway outside their respective locker rooms.

“They talk a little more,” Crowder said of the Wizards. “They say a little more disrespectful things than other teams. So that’s what escalated it.”

Boomshakalaka! Tuesday’s game should have a Knicks-Bulls, or at least Knicks-Heat, ’90s feel.
