BJ Penn retired when he became a shelf of his former (great) self. But eventually he got the itch to come back, so everyone got excited and the UFC gave him an opponent.
Unfortunately, legal troubles dashed all those hopes for a while. Then, when it seemed like the Hawaiian was in the clear, he used an IV, which is a big no-no under USADA rules.
So. Finally. Penn might really, truly, possibly, hopefully be coming back, and this time the UFC has given him Ricardo Lamas as a dance partner.
As per MMAFighting:
BJ Penn is not giving up just yet.
The UFC is currently targeting Penn vs. Ricardo Lamas as the main event of UFN Fight Night 97, which is scheduled to take place at the SM Mall of Asia Arena in Manila, Philippines on Oct. 15. The fight would take place in the featherweight division.
