UFC 141 Results: It's Time for Brock Lesnar to Go Back to the WWE

Brock Lesnar made his return to the cage against Alistair Overeem last night, and when the brief tilt was over he made his exit for good. Lesnar was knocked out by Overeem at 2:26 of the first round by an accumulation of solid strikes to the body.

Lesnar has always been an athletic freak of nature, with his size and agility making him one of the most dangerous big men in the world. While he's a very accomplished wrestler and entertainer, Lesnar's weakness in the cage became very apparent and relevant as he jumped deeper and deeper in to UFC waters. You cannot be a successful combat fighter without being able to withstand, run through and to some extent even enjoy getting punched and kicked.

It's one thing getting hit on the button and physically hurt to where physiology dictates you cannot persevere, but it's another thing getting hit and feeling pain. A true MMA fighter works through the pain to answer back, while a wrestler will retreat or shoot and look to avoid the next blow.

Lesnar has proven that he truly does not like to get hit and does not know how to effectively deal with it against elite fighters. He has proven he is a true wrestler. Last night he showed that after two major surgeries in two years, even his wrestling and physical dominance has indeed faded.

He did not charge out at Overeem like the confident beast he needs to be. He did not time his counterstrikes or takedowns to Overeem's shots because he was too busy retreating from the pain.

He did not close the distance with his trademark power and speed because he seemed tentative to engage. A tentative Lesnar is an ordinary Lesnar, and we saw an ordinary Lesnar last night.

At 34 years old and with many of his competitive years behind him, the big man from Minnesota's fire is out. Lesnar confirmed it as he retired in the cage post-fight. Four years, eight matches and a 5-3 record is what the MMA chapter will show when the book on Lesnar is written.

He came, he saw and he showed wrestlers and entertainers that there is a chance for them in the world of combat sports. There is only one prerequisite—you must not mind getting hit.

It's time for Brock to go back to the WWE where he doesn't have to worry about getting hit.
