The Miami Heat are anticipating a "dog fight" in their play-in matchup with the Philadelphia 76ers, according to forward Caleb Martin.

The 8th-seeded Heat face the 7th-seeded Sixers - who have listed Joel Embiid as questionable - at Wells Fargo Center on Wednesday.

Defeat for the Heat would see them in a win-or-go-home contest, but victory would see them open the playoffs against the New York Knicks.

Speaking ahead of the showdown with the Sixers, Martin is quoted by the Miami Herald as saying: "Everybody knows what's at stake going into that building, including them.

"We just expect a dog fight. We went through a lot of difficult games this year, over the last couple years, to get us prepared for these types of moments.

"So we'll definitely come in with the right mentality."

An injury-ravaged Heat ended the regular season with a record of 46-36, including a run of 7-3 across their final 10 games.

The Heat hope to have Duncan Robinson back after a four-game absence through a back injury, but Terry Rozier has been ruled out.

Miami and Philadelphia split the season series, and Heat center Bam Adebayo sees no reason why his side cannot come out on top this time around.

"We've been in a lot of big games before," he said. "We've all experienced it. We've been to the Finals. We understand what's at stake."
