Lavar Johnson injury cancels UFC on FOX 5 fight against Brendan Schaub

Ultimate Fighting Championship (UFC) President Dana White recently told his fighters to "tone it down a bit" so that no one got hurt in this last week before UFC on FOX 5, which emanates from the KeyArena in Seattle, Washington on Dec. 8, 2012.

Lavar Johnson apparently didn't listen.

The "Big" heavyweight pulled his groin while training and was forced to withdraw, leaving the promotion with no choice but to also yank his opponent, former Ultimate Fighter (TUF) 10 runner-up Brendan Schaub, from the "Emerald City" fight card.

"The Hybrid's" manager, Lex McMahon, talks to MMA Fighting:

"Brendan is very disappointed, but he is very dedicated and will be back to training. We will see how long Lavar is out and will assess Brendan's options. I'm confident the UFC will get Brendan back in the Octagon soon. "

Their absence will leave an empty slot on the FX Channel "Prelims;" however, the promotion has yet to determine if another fight will move up from the Facebook portion of the card to take its place.

Stay tuned.
