Dmitry Orlov (arm) out for worlds
Orlov said Tuesday he is set to travel to the United States for treatment.
Orlov's Russia teammate Andrei Loktionov was previously ruled out after sustaining a shoulder injury in a 5-0 victory over Switzerland on Friday.
Orlov's absence is a blow for Russia because two other defensemen -- Maxim Chudinov and Andrei Zubarev -- also have health problems.
