LeBron James was excused from the Cavaliers' morning shootaround Tuesday to attend to a "personal issue," a team spokesman said, but will play against the Milwaukee Bucks. The same team spokesman said guard Iman Shumpert is "probable" to return from a right knee injury that has kept him out for a week. On Monday evening, moments after Kyrie Irving and the Boston Celtics finished off the Atlanta Hawks, James posted to his Instagram account a meme from the children's cartoon Arthur of the main character clenching fist with the caption "mood." The Hawks beat the Cavs Sunday, and Irving is flourishing with the Celtics after three seasons and three Finals with James (and six seasons total) in Cleveland. Irving asked to be traded over the summer and the Cavs shipped him to Boston.
