B.J. Penn wants to keep fighting. UFC president Dana White would like to see the former welterweight and lightweight champion hang up his gloves.

While Penn remains on the UFC's active roster of fighters, he hasn't fought in well over six months and does not have a bout scheduled. The legendary Hawaiian mixed martial artist would like to return to 155 pounds for one last title run, but many onlookers believe Penn has nothing left to prove and has taken enough damage over the years.

Competing at UFC 31 in May 2001, Penn began his MMA career more than a decade ago, which makes him one of the longest tenured UFC fighters still looking to compete inside the Octagon today.

As Penn's long UFC career winds down, let's see where he stands among the active fighters with the longest running and uninterrupted stint in the world's top MMA promotion.
