Why do people say Amir Khan has a glass chin?

[Canadian Kid]

He got knocked out one time ... like big deal? Pacquiao been knocked out twice .... he has a good chin

[Rabbit ♠]

Those were body shots.

[Canadian Kid]

Those were body shots.

I know that. Still looks the same on the score sheet

[Garcia101]

He also got rocked by a guy who has like 8 KO's in his career.

[Dirk Diggler UK]

Those were body shots.

Only one was a body shot

[Forza]

1. he got k.o'd in round 1
2. hes british so he got no chin or heart just like hatton

[Seleção No. 13]

Pacquiao was also malnourished.

I think it's because Amir's butt chin literally has a crack on it.

[B.U.R.N.E.R]

He was hurt by Willie Limond.

[Blubba]

as good as Khan is as a boxer, he does have a suspect chin, he was shacken by and old MAB and paper champ Kotelnik stunned him with a shot.
