Chiefs bar Johnson from team activities

KANSAS CITY, Mo. —The Kansas City Chiefs have barred running back Larry Johnson from team activities pending an investigation into his use of a homosexual slur this week.

Johnson, a two-time Pro Bowl running back for the Chiefs, apologized today to his team, fans and the NFL "for the words I used."

"I regret my actions. The words were used by me in frustration, and they were not appropriate," he said. "I did not intend to offend anyone, but that is no excuse for what I said."

Johnson posted the slur on his Twitter account Sunday in a response to another tweet. On Monday, he said it again in refusing to talk with reporters, according to a recording made by the Kansas City Star.

The Chiefs and the NFL are investigating.
