Argentinian bantamweight Guido Cannetti has been pulled from next week’s UFC Fight Night 98 event following a flagged out-of-competition test issued by the U.S. Anti-Doping Agency.

Cannetti took to Instagram to announce his removal from the card, and MMAjunkie subsequently confirmed the potential violation with UFC officials.

“The UFC organization was notified today that the U.S. Anti-Doping Agency has informed Guido Cannetti of a potential anti-doping violation stemming from an out-of-competition sample collected on Oct. 5, 2016,” a statement read. “USADA has provisionally suspended Cannetti based on the potential anti-doping violation.”

“Ninja” Cannetti (7-2 MMA, 1-1 UFC) was expected to face Marco Beltran (8-3 MMA, 3-0 UFC) on the FS1-televised prelims of UFC Fight Night 98, which takes place Nov. 5 at Mexico City Arena. UFC officials are “currently exploring whether a replacement to fight Beltran can be arranged.”

In his Instagram post, Cannetti insisted he did not take any banned substance.

In the promotion’s typical statement, UFC officials issued a reminder that Cannetti is guaranteed a full legal review.

“USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case,” the statement reads. “It is important to note that, under the UFC Anti-Doping Policy, there is a full, fair legal review process that is afforded to all athletes before any sanctions are imposed. Consistent with all previous potential anti-doping violations, additional information or UFC statements will be provided at the appropriate time as the process moves forward.”
