Cung Le might be retired from combat sports but he's not done fighting.
The UFC and Strikeforce vet is a plaintiff in the class-action antitrust lawsuit against Zuffa, along with fellow fighters Jon Fitch and Nate Quarry.
Following his final professional bout against Michael Bisping Aug. 23 in Macau, China, Le tested positive for elevated levels of human growth hormone in a drug test overseen by the UFC.
Le was initially issued a nine-month suspension, which was then extended to a year. Le and his long-time manager Gary Ibarra protested the result and the suspension was lifted in late October.
