Amir Khan's father says his son will be turning professional "sooner rather than later" following a controversial loss for Amir's younger brother Haroon.
Haroon, 13, dropped a points decision to South Durham's Geoff Saunders in the semi-finals of the Schoolboy Championships in Liverpool on Saturday.
And Shah Khan said: "I'm 100% sure it was a backlash because of what's going on with Amir. It was outrageous.
"The Amateur Boxing Association is pushing us further and further away."
However, South Durham club secretary Tracy Saunders, who is also opponent Geoff's mother, disputed Shah Khan's version of events.
"Geoff has already beaten Haroon in March 2003, he clearly beat him Saturday and would be willing to beat him again given the chance."
