LeBron James was still sore on Wednesday after Tuesday's bout with leg cramps but said he "should be fine" by Thursday night.
The Heat plays the Thunder at 9 p.m. on Thursday in Game 5 of the NBA Finals. The Heat leads the series 3-1 and can clinch its second NBA championship in franchise history with a victory.
"I feel a lot better than I did last night--that's clear," James said during his post-practice news conference at AmericanAirlines Arena. "I'm able to walk up here even better than I did last night when I talked. I'm still a little sore because of the muscles just kind of being at an intense level, very tight."
James received treatment on his legs on Tuesday night and again Wednesday morning. He participated in the Heat's light practice.
James went down with a leg cramp in his quadriceps during the fourth quarter of Game 4 and was carried off the court but reentered the game to sink a clutch three-pointer with under three minutes to play. James, noticeably fatigued from the cramping, then left the game with under a minute to play.
"I'm going to use today as an opportunity to continue to improve with my legs," James said. "And also with the game being basically at midnight tomorrow night I have all day tomorrow, too, to prepare."
