Agree to disagree then u dont have any proof of him being knocked out, oda just had to cover other parts to he didn't show him the same chapter doesn't mean he was knocked out and the time between the chapters could be even 1 min, you dont know that, you just say it to push your agenda.
If Oda wanted to show that he wasn't affected at all, he would've made him get back up in the same chapter like what he did to Luffy when Apoo attacked him in this arc. But he didn't.
