Carlos Felipe flagged by USADA, out of UFC Sao Paulo fight against Christian Colombo

A Brazilian heavyweight prospect’s UFC career has been derailed before it even began.

Carlos Felipe failed a USADA out-of-competition drug test stemming from a sample collected July 29, the UFC announced Tuesday night. As a result of the potential anti-doping policy violation, Felipe has been pulled from his potential debut bout against Christian Colombo at UFC Sao Paulo on Oct. 28.

The UFC will seek out a replacement to face Colombo on the card, per the release.

Felipe (8-0) has won six of his eight career bouts by knockout of TKO, most recently against Sandro Bezerra on a Bahia regional card in May. Felipe, 22, made his pro debut in 2014.
