South Africa duo Bjorn Basson and Chiliboy Ralepelle will have to wait to learn their fate after a hearing reserved judgement over their positive drugs tests on Tuesday.
The pair, who returned positive tests for methylhexaneamine following a win over Ireland on November 6, both appeared in front of a judicial committee appointed by the South Africa Rugby Union.
Winger Basson, hooker Ralepelle, witnesses and SARU management all gave evidence in front of the committee during the three-and-a-half hour hearing.
But a decision could not be reached on the day, leaving the two players still waiting for a verdict, which will be announced after the committee has taken more time to deliberate.
A SARU statement read: "A judicial committee appointed by the South African Rugby Union (SARU) to investigate the anti-doping charges against Springboks Bjorn Basson and Chiliboy Ralepelle, reserved judgement in the case in Cape Town on Tuesday.
"A press conference to announce the verdict will be scheduled by SARU once the committee has completed its deliberations."
Basson and Ralepelle, who both play for the Bulls in Super 15, have been provisionally suspended since the failed tests. Their 'B' samples also tested positive.
Methylhexaneamine - a common ingredient in dietary supplements - was added to the World Anti-Doping Agency banned list at the start of 2009 but its classification was downgraded at the start of this year due to a number of inadvertent positive tests.
Following the test results, Springbok team management stopped the use of supplements and launched an investigation as they feared the whole of the team could have consumed the substance.
