<-- Watch the action here as Serena Williams exits the US Open in an unsportsman conduct.
Serena Williams is set to become the subject of an in-depth investigation after launching into a profane outburst that prompted her exit out of the U.S. Open.
Yahoo! Sports has learned that Williams will be asked to explain her actions and comments toward a female line judge at the end of her semifinal defeat to Kim Clijsters on Saturday night. A source revealed that representatives from tennis’ governing body – the International Tennis Federation – plus members of the Grand Slam Committee, which oversees the four major tournaments – will convene along with U.S. Open referee Brian Earley on Sunday.
