When it comes to fighter safety, does responsibility fall on UFC or commissions?

In the past year, the UFC has tackled out-of-competition injuries with
accident-insurance. The promotion has encouraged its fighters to
participate in a long-term study on brain trauma.

And just this month,
it attempted to address performance-enhancing drugs with a pre-screen
for its athletes.

But more should be done in-house, according to MMAjunkie.com medical consultant Dr. Johnny Benjamin.
