Freddie Roach has said that he will continue to prioritise Manny Pacquiao, should Amir Khan retain his services.
Khan suffered a knockout defeat to Danny Garcia in July and had suggested in the aftermath that he needs a more committed trainer.
The British fighter was referring to the joint training camps he shares with Filipino legend Pacquiao.
However, Roach has said that he will continue to prioritise Pacquiao.
"I have not heard anything official from them [Khan's camp]," Roach told Boxing Scene. "I heard they want to fight in December.
"No-one has told me whether I am in or out.
"If Manny fights in December, he takes priority."
Pacquiao is due to fight in early December, with Khan earmarked for a December 15 return.
A joint training camp is unlikely to be welcomed by Khan, who may seek a new trainer.
