Michael Johnson was hurt.

His opponent, Danny Castillo, had fired off a strong straight right hand that caught him flush on the chin and sent him flying backwards and scrambling to recover as fast as possible.

Castillo didn't make it easy on him, swarming in and unleashing a flurry of hammerfists with the deadliest of intentions. He was a shark in the water and Johnson was pouring blood like a leaky faucet.

He kept his wits about him and managed to survive, though, earning a one minute reprieve at the end of the round to regroup and regain his composure. He used that time to plot and plan his response, which turned out to be a sneaky little counter left hand that caught Castillo clean on the button.

When he fell out, it was Johnson who became the shark and he would not be denied his kill.

Four hard punches later and Castillo had his eyes rolled up and his arms stuck out, the referee the only thing standing in the way of his continued disposal.

From the brink of defeat to a sweet $40K for "Knockout of the Night."

Johnson was hurt but in the end, it was worth it.
