Amir Khan must forget about Manny Pacquiao and recover from a "bad knockout", says the Filipino's trainer Freddie Roach.
The Bolton fighter (31-4-KO19) stepped up to face WBC world middleweight champion Saul 'Canelo' Alvarez at a 155lb catchweight only to be flattened in the sixth round.
In the aftermath, Khan confirmed he will spend time with his family in the immediate future but also earmarked a bout with former gym-mate Pacquiao as "definitely a possibility" and expressed enthusiasm about going "straight into another big fight."
Pacquiao (58-6-2-KO38) called time on his legendary career after outpointing Timothy Bradley in April and his long-time coach Roach - formerly Khan's trainer - was quick to pour cold water on the idea of him facing Khan any time soon despite admitting the multi-division champion may fight again.
In an interview reported on boxingscene.com, Roach said: "That was a real bad knockout. After that kind of knockout, honestly I don't know about that [Khan fighting Pacquiao].
"That was a bad knockout and he's going to be under medical suspension for a couple of months, so I don't care what he says about Pacquiao right now.
"After that, I think he should take a break. Pacquiao is a senator now. I think he has one more fight in him but I haven't spoken to him."
Roach has previously claimed that when Pacquiao and Khan used to spar in his Wild Card gym, the Briton was knocked out cold several times.
