The All-Stars both were sidelined for the Heat's 116-109 triple-overtime victory in Atlanta on Thursday, but only James' sprained left ankle was healed enough to return to the lineup Saturday. Wade worked out before the game before the Heat decided he would sit out his third straight with a bruised left foot.
James Jones started at shooting guard.
"LeBron has played with this before, and he felt pretty good today in the shootaround with the intention of hopefully playing," coach Erik Spoelstra said during his pregame media availability. "Dwyane will go through the same process, but we'll have a discussion before making the final determination. He is feeling significantly better, though, after a couple days of rest."
James entered Saturday averaging 29.9 points, 7.7 rebounds and 7.4 assists for Miami, while Wade is averaging 18.8 points, 6.5 assists and 3.2 rebounds.
Anthony Morrow started for the Nets after having a partial root canal earlier Saturday.
Miller, who underwent hernia surgery in the preseason, will have his first full-contact practice on Monday, Spoelstra said.
"He's getting much closer to being cleared for full contact," Spoelstra said of Curry. "I said a couple days ago I watched his conditioning workout in our practice gym ... and he did a lot of our conditioning tests along with some very strenuous conditioning drills, and he's making really good progress."
