Serious slide? No. To me, he's the same Canelo I've seen throughout the years (except bigger and stronger).

The first knee issue was back in 2018... and reading about it, it's unclear as to how serious it actually was. Didn't seem to affect him after that.

I think it's a matter of aesthetics. After a series of opponents who were either woefully inadequate... or inexplicably went into the ring like a timid deer... Bivol was neither... and proceeded to make Canelo look like an ordinary plodder.

Which may in turn draw unwarranted focus to his knees.
