Khan returns against Alvarez in Vegas

London  - Amir Khan will return after a year long absence against Mexico's Saul 'Canelo' Alvarez in Las Vegas on May 7, the British boxer revealed on Tuesday.

"Delighted to announce i will be fighting @Canelo May 7th Cinco De Mayo, Las Vegas for the 155lbs @WBCBoxing title!" he posted on Twitter.

Alvarez (46-1-1) captured the vacant World Boxing Council middleweight title last November with a unanimous decision victory over Puerto Rico's Miguel Cotto.

Khan's last fight was in May 2015, a points welterweight victory over American Chris Algieri.

He said last month he had a "few options" for his next fight, but a catchweight contest at 155lbs with WBC middleweight champion Alvarez was not considered to be one of those possibilities.

Against Algieri in New York Khan improved to 31-3 with his fifth victory in a row.
