The next world anti-doping code, scheduled for 2015, will bid to prevent athletes who have been found guilty of doping from competing at the Olympic Games following the end of their suspension.
The International Olympic Committee (IOC) had included a similar ruling in its Olympic charter in 2008.
But the Court of Arbitration for Sport (CAS) ruled last October that this was an illegal sanction, and the IOC was forced to backtrack and abandon the stipulation before next month's London Olympics.
The 2015 world anti-doping code will seek to legalise a ban by implementing a 'Limitation on Participation in the Olympic Games', a first draft of the code revealed on Friday.
According to the provisional code, "where an athlete or other person has been sanctioned for an anti-doping rule violation ... as an additional sanction, the athlete or other person shall be ineligible to participate in the next Summer Olympic Games and the next Winter Olympic Games taking place after the end of the period of ineligibility otherwise imposed".
An Olympic ban could also be imposed on athletes deemed to have committed an anti-doping rule violation such as filing failures and missed tests, prohibited association.
"The body imposing the sanction may impose as an additional sanction ineligibility to participate in the next Summer Olympic Games and Winter Olympic Games taking place after the end of the period of ineligibility otherwise imposed."
"In deciding whether or not to impose this additional sanction, the sanctioning body shall, applying the principle of proportionality, consider the athlete or other person's degree of fault or the amount of substantial assistance provided."
The revision of the code follows a long period of talks which will likely come to a head at the fourth world conference on doping in sport, scheduled for November 13-15, 2013, in Johannesburg.
