Katie Taylor made a successful first defence of her WBA world lightweight title after a hard-fought battle with American Jessica McCaskill at York Hall.
The Irishwoman has made a superb transition into the professional ranks after a glittering amateur career and now has eight wins from eight after a unanimous points decision.
Taylor told Sky Sports: "It was very, very tough, probably the toughest fight of my career. I expected that, I had to be at my very best."

Taylor triumphed in a hard-fought battle with American Jessica McCaskill at York Hall
This was the first time a women's world title fight topped the bill on a major night of UK boxing
This was the first time a women's world title fight had topped the bill on a major night of boxing in the UK and the sold-out crowd in Bethnal Green roared on Taylor throughout.
The 31-year-old looked comfortable in the early rounds but McCaskill grew into the fight and landed a left hook in the sixth round to leave Taylor wobbling.
In the next round Taylor was docked a point for holding but she pulled away during the final couple of rounds and was a convincing winner on all the judges' scorecards.
Earlier in the night Conor Benn had got back up from the canvas to defeat Cedrick Peynaud.

The son of fans' favourite Nigel was floored twice in the opening round, but fired back in an unbelievable York Hall battle, knocking the Frenchman down twice in the final two rounds.
Benn, whose left eye was cut and his right eye badly swollen by the end, showed his heart and guts to get the decision 57-54, and move to 11-0-KO9.
