The team has said that Wade, who did some light shooting with teammates after the main workout, does not have an injury. He has been bothered by some fatigue over the last few games, which Wade and Spolestra said is the byproduct of physical series with both the Boston Celtics and Chicago Bulls.
"It was more of a preparation day and a mental day," Spoelstra said. "Some guys needed to have another day to recover from the last series."
In addition to Wade, several other Heat players including Udonis Haslem took it easy on Saturday. Wade got treatment on his left shoulder during Thursday's Game 5 victory to close out the Bulls in Chicago. Wade had surgery on the shoulder in 2008 and landed roughly on it in the Heat's first-round series with the Philadelphia 76ers. He said he was just getting standard treatment.
More at issue over the last several games have been Wade's legs. He hasn't had the same spring he's used to and is trying to use the four off days before the start of The Finals to get extra rest.
After averaging 30.2 points on 53 percent shooting in the series with the Celtics while effectively chasing Ray Allen on defense, Wade slumped a bit against the Bulls. He shot just 41 percent in the series and his scoring average dipped to 18.8 points.
"At this point of the season, no one is 100 percent," Wade said during the Bulls series. "If I was (hurt), I'm not going to tell you."
