Steelers' Bell unaware that he couldn't use goal post as celebration prop

Pittsburgh Steelers running back Le'Veon Bell's punching bag routine was one of a kind.

Bell scored a 3-yard touchdown against the Kansas City Chiefs during Sunday's 19-13 win and proceeded to pantomime a boxing routine, using the goal post as a punching bag.

The star running back was penalized 15 yards for the celebration.

"I guess I wasn't fully aware of that. Now I am," Bell said via ESPN's Jeremy Fowler. "So I just won't use the goal post next time. ...

"That was just kind of a spur of the moment right there. I did plan something (else), but I had forgotten once I scored. But I had seen the goal post and I had been doing a lot of boxing, so I just kind of boxed the goal post. That's the first thing that came in my head."

We'll have to wait see what Bell unfurls Sunday against the Cincinnati Bengals.
