Tim Means has been removed from a planned UFC Fight Night 83 main event bout with Donald Cerrone after an out-of-competition drug test came back for a possible violation.

The two were scheduled to meet later this month in Pittsburgh. In an official statement, the UFC said they are actively working for a replacement to meet Cerrone.

The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Tim Means of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection.

USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case. It is important to note that, under the UFC Anti-Doping Policy, there is a full and fair review process that is afforded to all athletes before any sanctions are imposed. However, because Means was scheduled to compete against Donald Cerrone on February 21 in Pittsburgh, there is insufficient time for a full review and proper promotion before the scheduled bout. As a result, UFC will announce shortly a replacement opponent for Cerrone on the UFC Fight Night card in Pittsburgh.

Additional information will be provided at the appropriate time as the process moves forward.

Means (25-7-1) has won five of his last six, losing only to Matt Brown last July via submission. He took to Twitter shortly after the news and seemed shocked by the result:
