Amir Khan and Devon Alexander both made the welterweight limit for Saturday's bout in Las Vegas. The British fighter weighed in exactly on the 147lb mark, while his American opponent also matched this weight for Saturday’s fight, live on Sky Sports. Both men displayed an air of confidence while they posed for pictures, with Alexander nodding at Khan as they exchanged some parting words. There is plenty at stake this weekend with the winner hoping to land a lucrative shot at Floyd Mayweather, the biggest name in boxing.
