"It feels better," Wade said. "I'll be ready to go (Tuesday)."
The Heat are set to take on the surging Celtics on Tuesday night in a game that could be a playoff preview.
The team hopes he will be ready to play after the All-Star guard participated in shooting and conditioning drills at the Heat's practice on Monday.
"We'll evaluate him and see what happens tomorrow," Heat coach Erik Spoelstra said.
The Heat have played without Wade for 11 games this season and are 10-1 in those games with the most recent win on Sunday against the Pistons. Wade is averaging 22.6 points, 5.0 rebounds and 4.7 assists this season with a player efficiency rating of 26.8.
Tuesday's game between the Heat and Celtics will be nationally televised on ESPN at 7:00 p.m. ET. The two teams have split their season series one game apiece and have two games remaining against each other in the regular season.
