Austrian cross country skier Johannes Duerr and Polish bobsleigher Daniel Zalewski were on Wednesday sanctioned by the International Olympic Committee (IOC) for failing drug controls at the Sochi Olympics.
Duerr, 27, has been disqualified from the men's skiathlon in which he finished eighth after testing positive on February 22 for the banned substance recombinant erythropoietin (EPO).
Zalewski tested positive for the stimulant phenethylamine on February 23, and has also been disqualified. The Polish four-man team placed 27th.
Austria's ski federation confirmed that Duerr would be barred from the federation for life -- a move it already threatened after the doping allegations in Sochi came to light.
The Polish federation have yet to decide on an eventual suspension for Zalewski.
Seven athletes tested positive in Sochi but Swedish ice hockey star Nicklas Backstrom was later cleared of wrong doing by the IOC and allowed to keep his silver medal.
