BJ's words:
"I’m at a concert going to meet a friend that I’ve known since we were really young kids and I’m over there and an acquaintance of mine, he gets mad about something, you know something was said or it was an old past thing and then he wants to fight about it," Penn says.
"I was like, 'No, no, I don’t want to fight, we’re friends, everything is cool.' He even walks outside and I’m thinking, this is silly I’m going to go get him, calm him down and get him to come back inside and enjoy the concert, we’ve got some other friends there."
"I walk outside to go give the guy a hug and then he hits me twice and I’m like, 'No, calm down!' I try to give him another hug and he hits me a couple more times and he hits me again."
"Finally my adrenaline picked up because he was hitting me so much so I said, 'Go ahead and hit me again.'"
Penn continues ... "I thought the guy would eventually just say forget it BJ, whatever, walk away, but he hit me -- and he hit me good and knocked me down -- and then when I got back up he tried it again and I just had to defend myself and that’s what you see in the second video."
Penn claims the videos were "edited" to cut out moments where Penn was trying to hug the other man. TMZ Sports did not cut a single frame out of the clips.
