Soon after the U.S. team arrived in Cardiff, Wales, to begin preparations for this week's three-day tournament at the Celtic Manor resort, both U.S. captain Corey Pavin and European counterpart Colin Montgomerie said players posting Internet comments could cause "trouble," the BBC reported.
"Tweeting and social network sites can get one into trouble," Montgomerie said. "It's not a ban as such, we've just asked the players not to and they agreed."
"The team has come to a consensus not to do it," Pavin said. "It can be a little bit distracting sometimes, and I think it is important to focus on the Ryder Cup and playing in the matches."
The BBC said U.S Open winner Graeme McDowell, Ian Poulter, Rory McIlroy and Francesco Molinari are regular users of Twitter from the European squad, while U.S. players Stewart Cink, Rickie Fowler, Zach Johnson, Hunter Mahan and Bubba Watson regularly "micro-blog" online.
