U.S. and European players have been banned from using Twitter and other social networking sites during the Ryder Cup.

U.S. captain Corey Pavin and European counterpart Colin Montgomerie say there will be a blanket ban in place this week to keep players focused on the three-day competition, which begins on Friday at Celtic Manor.

Pavin says the U.S. team agreed not to use Twitter because "it can be a little bit distracting sometimes."

Montgomerie says "we feel that tweeting and Facebook and all of these social sites ... can get one's self into trouble."
