The odds that Ultimate Fighting Championship President Dana White will allow former UFC heavyweight champion Brock Lesnar to leave the organization before his contract expires are most likely zero. The pay-per-view money that Lesnar represents to the UFC is just too big to let him walk away from a signed contract.

The fact is that Lesnar is a PPV monster. Of the top six UFC PPV events, Lesnar has fought on four of them. In fact, all six of Lesnar’s UFC fights are in the top 20 PPV events for the promotion. The lowest number of sells on a Lesnar card is 600,000 while the highest is 1,600,000. (Note: numbers for UFC 124 are not yet available.)

Rumors indicate that Lesnar has one fight left on his contract, the odds are good that he will have to honour that fight.

If he leaves the UFC when his contract expires, will he be considered a quitter? The short answer is yes, but first some history.

Late last year, Zach Arnold posted a detailed look at Lesnar’s past careers at Arnold found that Lesnar never stuck around when things started to get tough.

When he decided that he did not like the professional wrestling lifestyle of constant travel with World Wrestling Entertainment, he left after a long legal battle.

After his WWE career he tried out for the Minnesota Vikings of the NFL. The team liked what they saw in Lesnar, but not enough to make him a starter. Instead of taking the time to train harder and earn a spot on the NFL squad, he left.

Next up was New Japan Pro-Wrestling. Japanese legend Antonio Inoki signed Lesnar on to work as the promotion’s champion. Lesnar wrestled on a handful of cards, but was stripped of the belt due to “visa problems.” Arnold’s piece states that Lesnar had become tired of the travel between the U.S. and Japan and had just not shown up for a match.

After that he moved to the UFC. After his first loss, to Frank Mir at UFC 81 in August of 2008, Lesnar won four straight fights, capturing the UFC title in the process.

He had some trouble with Shane Carwin at UFC 116, but he was able to weather the storm and defeat a gassed Carwin in the second round of their bout.

Then came Cain Velasquez who dominated Lesnar from the opening bell to the 4:12 mark of the first round when the referee stopped Velasquez from inflicting any additional damage on an obviously defeated Lesnar.

After the fight, Lesnar got stitched up and went on a prolonged hunting trip. That was in late October. Since then, there has only been silence from the Lesnar camp.

There has been no mention of training for an upcoming fight, no statement that he would be back better than ever to get his title back, no "you beat me this time, but wait until next time" bluster, just a prolonged silence. Not exactly what you would expect from a “Viking warrior.”

Now it’s time to back up. Will Lesnar be a quitter if he leaves the UFC when his contract is up? As stated above, the answer is yes.

Lesnar did not enter the UFC to be a curiosity. He did not enter the UFC to earn a quick paycheck and he most certainly did not enter the UFC to be remembered as a cowering, bloody mess; the manner in which the Velasquez fight ended.

Lesnar entered the UFC to be the best ever, not a footnote that mixed martial arts fans will smirk at.

He told Joe Rogan early in his career that he was “ready for war.” Lesnar should be reminded of that statement, because at this point it seems as if he is waving the white flag of surrender.
