BJ Penn talks about another comeback on Fuel TV.

Dear BJ Penn,

Please don’t come back, unless it’s at 155 at least. Also: don’t come back because you think you need to prove anything. Thirty years from now you will still be considered one of the greatest fighters to walk the planet. You will always be amazing, don’t fight half-hearted, I don’t want to see the Rory MacDonald fight ever again.
