The Detroit Lions released William Powell from the practice squad today, ending his short trip to London. Powell, who was with the team when they flew to London, was informed today after former Lion safety Jerome Couplin cleared waivers. It is expected that the team will fly Powell back to Detroit as soon as possible. Lions coach Jim Caldwell stated that it was a tough decision to do that to Powell, but at the same time the NFL is a business and the move was necessary to get the personnel they need for practice this week. A corresponding move is expected shortly.
