Josh Koscheck sent a text message to UFC President Dana White after his first-round knockout loss to Tyron Woodley Saturday evening, and it sounds like the longtime welterweight star will walk away from the sport.

According to ESPN's Brett Okamoto:

This, of course, comes with a huge question mark:

How much do we trust a text message sent just moments after a crushing defeat?

As Okamoto reported, White said, "Fighters say things after fights," and an emotional combatant like Koscheck is predisposed to such a hasty decision.

While this report may prove to be nothing more than an overreaction on Koscheck's part, retirement does make sense for the former The Ultimate Fighter Season One standout.

The loss against Woodley marks the first time Koscheck has dropped three straight fights in his career, and he was knocked out in two of these three defeats.

Now well outside of the division's top 10, it is hard to imagine Kos restarting and piecing together another run at the top after a lengthy career against the sport's toughest fighters.

If Koscheck does decide that his UFC 167 trip to the Octagon was his last, he will be remembered as a smack-talking wrestler who helped the sport grow and prosper.

While he was despised by many, Kos moved the needle for the UFC, and he proved time and time again that he could compete at the sport's highest level.

Despite never hoisting UFC gold, Kos will go down as one of the best 170-pounders of all time and one of the most polarizing figures to ever fight under the UFC banner.

If this is it, enjoy the vacation Mr. Koscheck. You've earned it.
