FLORHAM PARK, N.J. - New York Jets wide receiver David Clowney was "very shocked" after someone hacked into his Twitter account earlier this week and sent out a series of vulgar messages.

Clowney has had his Twitter account locked since the expletive-filled tweets went out to friends and fans Monday, and the receiver says he might not use the social networking site again.

The Jets issued a statement Monday night alerting fans that a "rogue tweeter" was sending out R-rated messages under Clowney's account. Clowney, who has more than 6,700 followers, confirmed the messages were not from him - including a direct message in which he suggested a fan to "kill yourself dude."

The offensive tweets have since been removed from Clowney's home page.
