Yushin is now 36 years old and has been fighting professionally for 15 years, since 2002.
To say he's out of his prime is an understatement. He continued to lose immediately after being scuttled from the UFC and fought at welterweight several times. Recently he's been fighting cans, which is an appropriate level if he wants to keep doing this for a living.
Booking Yushin to fight a top 10 light heavyweight was dangerous and stupid. This sort of thing should never have been sanctioned.
We are all very lucky he just got put away quickly with a choke instead of getting seriously hurt.
Shame on the UFC.
