James hit a game-winning buzzer beater in Game 4 to tie the series at two games apiece.
James said has been receiving around-the-clock treatment on his ankle, according to Windhorst. The four-time MVP rolled his ankle during the third quarter of the Cavaliers' 86-84 Game 4 win over the Bulls on Sunday, when Derrick Rose attempted to take a charge on James on a fast break.
Cleveland has been playing without forward Kevin Love, who is out for the season with a dislocated shoulder. Guard Kyrie Irving has battled a strain in his right foot and tendinitis in his left knee during the series.
During the regular season, the Cavs finished 53-29, second in the Eastern Conference, with James averaging 25.3 points, 7.4 rebounds and six assists. They swept the Boston Celtics in the first round of the playoffs.
James has led the team with 26.5 point, 10.1 rebounds and 7.8 assists in the postseason. He scored 25 points with 14 rebounds and eight assists in Game 4.
