Dwyane Wade had his knee drained prior to Game 3, according to multiple sources.
Wade has downplayed the extent of his left knee injuries over the past few weeks.
Wade declined to comment on the procedure after Game 4 other than to say, "If I'm in uniform, I ready to play."
Wade said the 48 hours of treatment and time away allowed him to regroup for Sunday's critical game.
"The last two days have been mental," Wade said. "It was great for me just getting away and to get that energy that I needed. I know I was struggling on the offensive end, but I didn't want that to affect my overall game."
