The entire United States 4x100m relay team have been stripped of their London 2012 Olympic silver medals as a consequence of Tyson Gay's drugs ban.
Former 100m and 200m world champion Gay was suspended for a year after testing positive for a banned anabolic steroid.
The 32-year-old returned his London 2012 medal when his suspension was announced in May 2014.
Now the International Olympic Committee has told US Olympic bosses that the whole team must return their medals.
