TALLAHASSEE, Fla. -- Florida State's football coach has told his players they can't use their Twitter accounts for the rest of the year.

Jimbo Fisher's move came after some players tweeted objectionable material on their Twitter sites in recent weeks, including one that quoted rap lyrics about killing police officers. The third-year Seminole coach wants his players to be as focused as possible and believes that social media can be a distraction, especially during the season.

Many players shut down their participation on Twitter last year after an early three-game losing streak wiped out their championship hopes.

Florida State is a runaway preseason favorite to win the Atlantic Coast Conference this year behind fifth-year senior quarterback EJ Manuel and a veteran defensive unit that ranked among the nation's best last season.
