Miami Heat star LeBron James has apologised to teammate Mario Chalmers for their altercation during the win over the Indiana Pacers on Wednesday night.

The pair appeared to exchange heated words on the bench during a time-out before James got up to confront his teammate.

"I love @mchalmers15 like a blood brother! I was wrong and apologized to him! We good and will always be good. I ride with him any and every day," he said on Twitter.

James was seen on camera during the game apologising to the point guard after the incident.
