Raiders coach Hue Jackson asked the NFL why a penalty wasn't called on Lions defensive tackle Ndamukong Suh for removing his helmet after he blocked Sebastian Janikowski's 65-yard field-goal attempt as time expired last weekend. Players can be penalized 15 yards for removing their helmets on the field of play. That could have given Janikowski another field-goal try, this time from 50 yards. Jackson said league officials told him that the game was over when Suh removed his helmet, so no penalty was called. "They had blown end of regulation," Jackson said. "... So it's like going to shake somebody's hand. But it looked like it was close. It was inconclusive is what they said."
