"Larry Johnson didn't say much, but those few words Monday from the Kansas City Chiefs running back further stoked a fire that had been ignited the night before.

Hours after the Chiefs lost 37-7 to San Diego on Sunday, Johnson made several controversial remarks on Twitter directed toward his coach, Todd Haley, and Haley's lack of football-playing experience.

A message posted on Johnson's Twitter profile about 7 p.m. stated: "My father played for the coach from 'rememeber the titans'. Our coach played golf. My father played for redskins briefley. Our coach. Nuthn."

Johnson continued the postings and, in later responses directed toward his Twitter followers, included inflammatory remarks about gays. In a reference to someone's profile picture, Johnson called it a "fag pic" and called the person a "Christopher street boy," a reference to a predominantly gay and lesbian area in New York's Greenwich Village.

Then Monday in the Chiefs locker room, Johnson used another slur after saying he wouldn't speak to reporters.

Johnson, sitting down, told reporters that "I'm not talking till Thursday," his usual day of speaking with the media.

Then Johnson turned away and whispered, "Get your faggot ass out of here."

Haley was asked at his news conference later Monday about Johnson's comments and said the matter was being investigated by the team.

"How our players conduct themselves with and through the media in a public setting is very important to us as an organization," Haley said after being asked about Johnson's use of the slur."
