UFC Heavyweight Justin Ledet has been flagged by USADA for a ptoential violation stemming from a sample collection on Jan. 12.

The UFC announced the news on Wednesday.

Ledet (8-0 MMA, 2-0 UFC) has been perfect in the UFC, and his professional MMA career thus far. After going 6-0 outside the UFC, Ledet made his promotional debut and won a decision over Chase Sherman. The Texan then stopped Englishman Mark Godbeer via submission at UFC Belfast.
