The NBA fined three players stemming from their roles during a game this week between the Dallas Mavericks and Charlotte Hornets.
James Johnson was fined $40,000. For the Hornets, Cody Martin lost $25,000 and Caleb Martin $20,000.
The incident happened with about 2:40 left in Wednesday's game, a 118-99 victory by Charlotte.
The NBA said Johnson deliberately pushed Cody Martin out of bounds, "aggressively confronting him and initiating the incident."
