"Polish weightlifter Tomasz Zielinski is set to receive an Olympic bronze medal despite finishing ninth at London 2012 - and being currently banned himself.
Six other athletes from the men's -94kg final tested positive for performance-enhancing drugs when their 2012 samples were retested this year.
They included all three of the original medallists - Ilya Ilyin, Aleksandr Ivanov and Anatolie Ciricu.
Zielinski was sent home from Rio 2016 after a failed drugs test in July."
