However, before those two square off in the Octagon, one thing Penn decided to do was to get involved in another bar fight.
TMZ Sports has obtained video of the UFC star fighting an unnamed bar patron at the Lava Shack this past Tuesday Night.
Video of the incident can be seen below:
The video shows the former two division UFC champion mounting an unnamed bar patron while attacking said person with a plethora of punches. Security did eventually break the fight up and police were called to the scene, but Penn has not been arrested as of this writing.
It is unclear at this time as to what exactly started the fight, but the video above clearly shows Penn reigning down strikes on the unnamed male.
This is not the first legal trouble Penn has found himself in, as the UFC star has been involved in a separate bar fight earlier this summer, allegedly threatened a farmer with a machete and allegedly engaged in domestic abuse with a girlfriend.
TMZ Sports has provided a second update, which shows Penn getting knocked out after eating a two punch combination from the unnamed bar patron. This second video shows a continuation of the bar fight, which TMZ Sports had previously obtained footage of.
A video of the second portion of the fight can be seen below:
