Canelo Álvarez knocks out Caleb Plant in 11th round to win undisputed super-middleweight championship – as it happened

• Alvarez stops Plant in 11th to win all four title belts at 168lbs
• Mexican adds IBF belt to WBA, WBC and WBO championships

Round 4

Early on Canelo lands a massive left hook upstairs on Plant as he's pinned on the ropes and the crowd springs to its feet. But he's able to escape from danger under a hail of punches and resumes his game plan of jabbing away. He's outthrowing Alvarez by a more than two-to-one margin. Plant is very slippery and making Canelo miss a lot, but maybe not doing a whole lot to win himself other than weather the onslaught. Close round.
