However, according to MMAMania.com, talks of his sudden departure seem to be premature and his Brazilian Jiu-Jitsu coach, Alana Goes, said Penn would return to the UFC in the future.
Goes posted photos of "The Prodigy" on his Facebook page and said that Penn personally told him that he would continue his fighting career.
The Hawaiian has gone 1-3-1 in his past five bouts while competing at both 155 lbs and 170 lbs, respectively. Prior to his current run, Penn was the reigning UFC lightweight champion and dominated the division for nearly two years with victories over Sean Sherk, Kenny Florian and Diego Sanchez.
Penn has historically never fared well as a welterweight, partially due the size disadvantage, while facing fighters such as Georges St-Pierre and Jon Fitch.
However, Penn is still relatively young at 32-years-old and he still can compete against some of the top fighters in the world, but time will tell if, and when, he does decide to return to the Octagon.
