UFC veteran Dan Lauzon has proven once again why it's never a good idea to get into a street fight, even if you're a professional fighter.

Because your opponent(s) may be packing a knife.

According to a report from The Enterprise, Lauzon got into an altercation with a group of men and was stabbed in the shoulder. He was then transported to a local hospital for treatment.

His brother, current UFC lightweight contender Joe Lauzon, wrote a blog post today in which he said, "everything is okay and it wasn't a big deal as was originally thought."

However, in his rush to get to the emergency room to check on his sibling, "J-Lau" rolled his ankle and suffered what he said doctors called a "bad sprain." Photo of the injury after the jump.

We've learned something today -- don't get into fights outside of a local pub with a group of men. You might end up getting shanked and your brother might hurt himself in his rush to the emergency room to check on you.

Be safe out there, Maniacs.
