ASHBURN, Va. (AP) — Washington Redskins receiver Joshua Morgan says he’s not concerned about the death threats on Twitter that followed his fourth-quarter blunder in the loss to the St. Louis Rams.

Morgan talked Wednesday about the venomous tweets he’s received since his unsportsmanlike conduct penalty for throwing the ball at another player. The penalty cost the Redskins valuable field position during the team’s final drive in Sunday’s 31-28 defeat.

Morgan says the only thing he takes seriously “is football and my family and nothing really scares me. I’m from D.C.”

Morgan says he’s been fined over the play but doesn’t know the amount.

He says there won’t be a repeat of the incident, saying: “Especially with coach Mike Shanahan, none of us are dumb enough to make the same mistake twice.”
