Can we believe RD.1 had to do with it being Sergios biggest fight to date?

While I agree with the bolded it seemed to me that Sergio was unable to move, he was constantly out of balance, yet didn't look hurt.

When down he recovered quickly, he wasn't out on his feet like Bradley vs Provo, but still couldn't move, couldn't punch,

Didn't look hurt? My goodness, man.

Sergio himself has confirmed it. It wasn't the knee.
