The Hornets and Heat, tied at 29-34, will meet twice in 12 days starting Wednesday night at the Spectrum Center in Charlotte.
Charlotte has lost eight of its last 11 games, including a 118-108 decision to the Portland Trail Blazers at home.
"I think at this point in the season there's a lot of games that we wish we would have had, so we can't look back at anything," said Marvin Williams." You just have to focus on what's in front of you."
Miami, who's recent play is very much a positive sign, will be without guard Goran Dragic (left calf strain) will not play tonight against Charlotte.
Dwyane Wade, third on the team in scoring at 14.3 points per game, became the most prolific shot-blocking guard in NBA history, one more than Michael Jordan had.
Charlotte is led by Kemba Walker's 25.1 points and 5.8 assists per game.
