The Bolton-based boxer is set to take on Carlos Molina in Los Angeles on Saturday in a bid to get his career back on track after two consecutive defeats.
And fans wishing to see the bout will get a chance to witness the action first hand if the bring an unwrapped, unopened toy to promoters. Those toys will be given to the neediest children in the City of Angels.
So long as they toy's value is £15 or more, the generous fans will be given an equally-generous gift of two tickets for the fight.
It seems a monumental bargain considering that top-price seats for the bout at the LA Memorial Sports Arena go for in excess of £100.
Truth be told, Khan's promoter Oscar de la Hoya is using the scheme as a way of filling what would otherwise be unsold seats in a 17,000-capacity arena.
But given that Khan's camp could just as easily have cut prices a little and hoped to bring in a few more dollars, it remains a genuinely heartwarming tale to show that even the invariably greed-driven sport can still give something back.
“I am looking forward to distributing the toys to those families who need them most," said de la Hoya.
Khan will need more than a few happy children to save his career, however: following his surprise defeats by Lamont Peterson and Danny Garcia, he is in desperate need of a win to revitalise his chances of challenging for world titles again.
The 26-year-old has been working hard with new trainer Virgil Hunter after dumping the legendary Freddie Roach - who Khan felt never gave him enough attention before fights.
The 2004 Olympic silver medallist and former WBA and IBF light welterweight champion is confident that his new coach will put him on the right track, and the switch has also been able to train alongside current super middleweight champion Andre Ward.
"He is a great fighter who is very skilful. He's sly in the ring," Khan said of Ward.
"If I can learn a few things from him and pick up what he has to offer, then I am going to do that. He has the skill of a boxer who can make it easier for himself and still be classy fighter.
"It has been great to be in camp with him."
