The WBO is to review the footage and official reports of Paul Smith's super-middleweight title fight with Armenian-German Arthur Abraham.
Liverpudlian Smith, 31, lost to Abraham on a controversial points decision on Saturday and has called for a rematch.
Judges scored the contest 117-110, 117-111 and 119-109 in Abraham's favour.
The WBO tweeted: "The #WBO is waiting to receive the assigned supervisor's report and replaying the fight before giving an opinion on #AbrahamSmith."
After the fight in Kiel, Germany, Smith described the decision as "disgusting".
His promoter Eddie Hearn tweeted the scorecards were: "some of the worst I have seen".
The WBO could overturn the result or deem the bout a no-contest.
It could also enforce a rematch by making Smith mandatory challenger.
Smith claimed Abraham promised a return bout at the post-fight press conference and the Liverpudlian is hopeful the two-weight world champion will stick to his word.
"The best outcome for me is for the WBO to watch the fight, sort the judges out, get three neutral and competent judges in, make me mandatory challenger and put the fight up for purse bids," he told Sky Sports.
"Let's do it again and have an immediate rematch."
