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.
Fans have now commented on Khan's stature after the pair worked out in public, with one fan writing: "He is too skinny he is going to get decked by Kell Brook.
Another fan wrote: "He looks proper weak there is no muscle on him. He is going to really struggle to make a dent in Brook."
One fan agreed: "Khan is looking really weak, doesn't look right at all. He looks bad at that weight."
However a fan disagreed: "I mean Khan looks great here. He looks like he has had a very good camp. Brook looks good but weight drained. This could be a big deciding factor here and BoMac knows that."
Another fan continued to comment on weight: "Khan is so slim, definitely too slim he is getting smacked."
One fan pointed out other fighters weights: "People who are obsessed with physical appearance before and during a fight don't know anything about boxing. Look at Tyson Fury and Andy Ruiz."
Khan and Brook will be forced to pay a six-figure fine if either fighter misses the catchweight of 149lbs this week.
Despite fans concerns, Khan has expressed his delight at the fight finally being made and is confident he will make the limit.
"Yeah definitely we have trained so hard for this fight," Khan said. "There is not one day I have had that is easy.

"Guys I am ready honestly, I have never been this fit and strong and I can't wait to show everyone who the boss is."
The pair have previously disagreed over issues such as weight and who is the 'A-side' in the fight which has prevented the bout from happening.
However the fight now looks set to take place despite both fighters being considerably out of their prime years.
Brook has previously expressed his own concerns about the weight limit of 149lbs with his comfortable weight seen at around 154lbs.
But he has now insisted that he will be able to make the limit for fight night this week.
"I am there with the weight, I could have made the weight three of four week ago. I am very comfortable with where I am at, the 19th is right there now.
"I am genuinely happy I am not putting a poker face on, I am just enjoying it all now as I have put the hard work in being away from my family over Christmas.
"It will be all worth it on Saturday night when I have my hand raised high."
