Eddie Hearn was 100% confident we would still see Conor Benn vs. Chris Eubank Jr, but admitted it might not be Saturday.
The British Boxing Control Council [BBBoC] ended the fight after it emerged that Benn had returned a positive drug test in August.
He was found to have traces of clomiphene, a female fertility drug, in a Voluntary Anti-Doping Association test.
He has since passed all UK doping tests and both fighters were happy for the fight to continue.
But the BBBoC banned the fight and said they would not sanction the fight.
Matchroom boss Hearn is exploring options in hopes the fight will take place at the O2 Arena on Saturday.
Speaking to talkSPORT, he said: “Best case scenario everyone is happy with the situation and the fight continues on Saturday. Worst case scenario is a postponement and we are selecting a new date this year.
“We will always see this fight 100%. It’s bigger than ever, but we’d like to see it on Saturday.
The test was carried out in August but was not made public until days before the fight was due to start, leading to huge uncertainty and confusion as the two boxers embarked on their public workouts.
When asked why, Hearn replied, “The results are confidential between the parties. The results were therefore shared with Matchroom, Wasserman, Team Benn, Team Eubank and the British Boxing Board of Control.
“You are guilty in this case before you prove that you are not. We had that with Dillian Whyte where the whole world hung him up to dry and then was found not guilty.
“We have to go through this process with this failed test. There are no doping violations at this time. We are aware of the levels, possible contamination and all that.
“It’s not something that’s publicly reported. UKAD is publicly reported and all of his UKAD tests have been negative.
It is believed that the two fighters spoke to each other and agreed to continue, which Eubank Jr denied.
Hearn added: “They spoke when they found out the test results because Conor Benn was adamant he wanted to speak to Chris Eubank Jr.
“Conor was one of the people who wanted to implement additional testing for this fight. It’s extremely frustrating and he wanted to make his point to Chris Eubank Jr.
“The conversation is nice, but the medical opinion is much better.”
Hearn said he was talking with lawyers about their options and saw no reason why Benn shouldn’t be allowed to fight because VADA testing is not recognized by the BBBoC.
He continued: “We were informed a few days ago of an analytical finding from a test. This information has been shared with Team Benn, Team Eubank and the British Boxing Board of Control.
“Team Benn investigated the tests, levels, bloodwork, everything with medical experts and were happy to continue the fight.
“The test was carried out by VADA, which is not recognized by the British Boxing Board of Control, only UKAD is, which is their testing agency, which has tested Benn several times during this training camp and they were all negative.
“In this regard, Conor Benn is not suspended by the British Boxing Board of Control, there have been no confirmed breaches, but he clearly has to follow a process to explain why there were time marks in a VADA-test.
“Really from here the British Boxing Board of Control has decided, at this time, that they don’t want to sanction the fight but have not suspended it.”
