It annoys me how little credit Khan is getting in the light of this though.

The cut was bad but plenty of fighters have been cut or injured worse than that and still fought on and won.

Look at the hell Vargas gave Mosely with only one eye, how Sergio Mora rallied against Peter Manfredo after suffering a horrific cut early, how Arthur Abraham beat Edison Miranda with his jaw hanging off of his face. Danny Williams beating Mark Potter with a dislocated shoulder.

Barrera got DOMINATED from the very first bell.

You can argue that a prime Barrera kills Khan, that a Barrera fighting in his proper weight class kills Khan but its an inescapable fact that a 35 year Barrera after 70 fights, fighting at lightweight against a younger, faster, stronger man gets DOMINATED.

Sad, but true.
