US Open - Serena facing tirade

A source revealed that representatives from tennis's governing body the International Tennis Federation plus members of the Grand Slam Committee, which oversees the four major tournaments will convene along with US Open referee Brian Earley.

The group is expected to review video footage of the incident, seek clarification from the line judge and most likely hand down a heavy fine to Williams.

A representative from the WTA Tour is also expected to be included, although the Tour does not have jurisdiction over Grand Slam events.

Williams lost her cool after being called for a foot fault on a second serve while trailing 15-30 and 5-6 in the second set. Clijsters won the first set 6-4.
