UFC: 5 fighters with the most losses inside the Octagon 

=2 BJ Penn (11 losses)

BJ Penn - Not won a UFC fight since 2010

BJ Penn is set to make yet another return to UFC at UFC 232 versus Ryan Hall. That fight will inevitably end the same way as Penn's previous five fights for the promotion; in defeat.

Penn remarkably has also lost 11 times inside the Octagon, a figure that may soon increase to 12. It is a far cry from Penn's early years fighting for UFC, where he lost just one of his first eight fights for the promotion, winning the Welterweight Championship in the process.

Penn's first UFC return in 2006 saw him lose two fights in a row to the legendary George St. Pierre and Matt Hughes before bouncing back in style with five wins in six bouts which included a reign as Lightweight Champion.

However, Penn has rarely tasted success since and at 39 years of age with no MMA wins since 2010, it is unlikely the Hall of Famer ever will again.
