Cleveland Cavaliers forward LeBron James will likely miss the remainder of the preseason, ESPN reports.

James, who has been battling a sore back, received an anti-inflammatory injection in his back earlier this week, David Griffin, the general manager of the Cavs, told ESPN.

Cleveland is set to kick off the regular season against the Chicago Bulls on Oct. 27. Before then, the Cavs have two exhibition games: Oct. 18 against the Toronto Raptors and Oct. 19 versus the Dallas Mavericks.
