In his recent fights, like vs Andy Lee, JCC Jr has been impressive but having only caught a cursory glance at his resume I was wondering if I could get a little help.

How good is Chaves' chin really? I tried (swiftly) googling knockdowns, but mainly got links to his father being knocked down vs Randall.

So my question is thus: has Chavez Jr been chin-checked? and by whom? Has anybody truly made him wobble? Sorry if this is a glaring display or my lack of knowledge but just if there's anyone out there on the site who's followed him who'd like to share then I'd be very happy to listen. Thanks.
