ASHBURN, Va. — Washington Redskins rookie linebacker Robert Henson has apologized for calling the team's fans "dim wits" on his Twitter feed.

He says Monday he updated his Twitter and Facebook accounts to apologize "not because I'm scared, but just because it was the right thing to do."

Henson, a sixth-round draft pick from TCU, has been inactive for both games this season.

Home fans booed the Redskins often Sunday during a 9-7 victory over the St. Louis Rams. Afterward, Henson tweeted: "All you fake half hearted Skins fan can .. I won't go there but I dislike you very strongly, don't come to Fed Ex to boo dim wits!!"

Henson also tweeted: "The question is who are you to say you know what's best for the team and you work 9 to 5 at Mcdonalds."
