Lamont Peterson vs. Amir Khan Rematch off

Late Monday evening, news broke out that unified WBA and IBF light-welterweight champion Lamont Peterson (30-1-1, 15 KOs) tested positive for synthetic testosterone in a March drug test. This now puts his past performance into question and his career on hold.

It would now seem that one of the worst possible outcomes from this is happening: the fight has been cancelled. 

Richard Schaefer, Golden Boy chief, stated that the rematch was up in the air and would go on if allowed by the Nevada State Athletic Commission. It seems, though, that Peterson won't be allowed to fight as his license was taken away due to his positive test. He's no longer a licensed boxer in the state of Nevada and can therefore not fight May 19th.

Amir Khan later confirmed this on his Twitter feed, stating:

"

The fight is off! sorry everyone the only person to blame is @kingpete26 I'll be looking for a opponent to fight June 30th

—Amir Khan ‏ (@AmirKingKhan)

"

Lamont Peterson and his team already put in a statement to challenge the ruling, but it seems unlikely that Peterson will get his license in time to fight. This is a huge blow to the sport as a boxer is busted for using a banned substance, strengthening the call for improved testing.

Team Khan is currently searching for a replacement for June 9th and names thrown around include Marcos Maidana, Miguel Vasquez, Joan Deguzman and Devon Alexander.

Now, people who've already bought their tickets, airfare and hotel will be cheated out of their pockets for Peterson's mistake. 

Lamont's mistake not only hurt his career, but also the pockets of the promoter and the fans.
