Hospital officials said 26-year-old Alexander Galimov died Monday morning of the severe burns that covered about 90 percent of his body.
The crash last week outside the city of Yaroslav took the lives of 44 people, including 37 players, coaches and staff of the local Lokomotiv Yaroslavl ice hockey club.
The only other person to survive, a member of the flight crew, was said to be undergoing treatment in Moscow.
The hockey team was heading to Minsk, Belarus, to play its opening game of the Kontinental Hockey League season when the three-engine plane crashed into the Volga River bank shortly after takeoff and burst into flames.
