The Sacramento Kings have been here before.

They know getting through the NBA play-in tournament from the elimination bracket won’t be easy, but a first-round victory over the Dallas Mavericks on Wednesday at Golden 1 Center would give them a chance.

“It’s very important game,” Kings center Jonas Valanciunas said. “It’s one game, do or die, so we’ve got to be prepared. We’ve got to be ready. It’s going to be hell.”

The Kings are one of four play-in teams vying for the last two playoff berths in the Western Conference. The No. 9 Kings will play the No. 10 Mavericks with the winner going on to play the loser of Tuesday’s game between the No. 7 Golden State Warriors and No. 8 Memphis Grizzlies.

If the Kings can find a way to win both games, they will advance to the playoffs as the No. 8 seed in the West with a first-round matchup against the top-seeded Oklahoma City Thunder.

“Super excited for the guys and the city to able to qualify, and now we are — one at a time — two wins away from getting to the next step of our journey,” interim Kings coach Doug Christie said.

The Kings on Sunday evening were offering presale access for tickets to their first play-in game Sunday at Kings.com.

The Kings (40-42) finished ninth in the West to secure a home play-in game against the Mavericks after beating the Phoenix Suns 109-98 in Sunday’s regular-season finale. The Mavericks (39-43) finished one game behind the Kings after losing three of their last four games.

The Kings went 3-0 in the season series against the Mavericks. They played the Mavericks once following the blockbuster trade that sent Luka Doncic to the Los Angeles Lakers in exchange for Anthony Davis, but Davis was out with an injury.

Davis has only appeared in nine games for Dallas, but the Mavericks are 6-3 with him in the lineup.

“We have homecourt advantage,” Sabonis said. “The fans are going to do their job and give us energy, and we’ve got to lock in. They’re a very tough team. Forget about their record. Everyone’s back, everyone’s healthy, and they’re a big, physical team. We’re really going to have to figure out how to get this (win).”

The Kings fell short of the playoffs last season. They beat the Warriors in a first-round play-in game before losing to the New Orleans Pelicans in a game that would have sent them to the playoffs for the second year in a row.

Kings guard Keon Ellis said the team understands the urgency of the situation.

“We all know it’s a one-game elimination, so it’s kind of a little bit more pressure than a playoff series,” Ellis said. “In the playoffs, you lose one, you still have three more losses before you’re out. But in a game like Wednesday, that’s your one and only shot, so I think everything has to line up and connect for us because there’s no second chance at that.”
