Fans have observed that Amir Khan is looking "skinny" after he worked out ahead of his grudge showdown with Kell Brook.
The British pair will finally settle their long-term rivalry in Manchester this weekend in front of 20,000 fans after the event sold out in record time.
Khan and Brook have agreed to meet at a catchweight of 149lbs in their contract after failing in previous years to agree a weight limit for their clash.
