Canelo Alvarez drops Amir Khan with one devastating punch

Amir Khan kept the Mexican boxing fans in Las Vegas quiet for the majority of five rounds Saturday night against Canelo Alvarez, but the lineal middleweight world champion finally connected with one brutal punch that ended the bout instantly in the sixth round. 

Khan went up two weight classes to take on Alvarez at a catchweight of 155, and though Khan’s speed frustrated Alvarez early, he couldn’t cope with Alvarez’s world class power. After Khan arguably won the first four rounds – the official scorecard was split at the time of the KO – Alvarez began to find his range in the fifth round and punished Khan with body shots. All it took was one hook in the sixth round to give Alvarez his 47th career win. 

Khan was out cold on the canvas, and Alvarez immediately kneeled to make sure his opponent was okay. Khan was surrounded by medics, but after a few moments got to his feet and said that he was "OK."

Alvarez will now be required to face knockout artist Gennady Golovkin later this year or surrender his WBC title. HBO’s Max Kellerman asked Alvarez in the ring if he’s now willing to take on Golovkin, who was sitting ringside.
