Short answer: nothing.

As I'm watching- 2:09 round 2.
Jab to the body sets up killer Right hand, Floyd IMMEDIATELY clInched that arm.
Took him 2-3= seconds to unlock that arm by literally throwing Floyd off.

Throws right hand two more times- Floyd moved in to smother (where U suggest upper cut?)

1:56 Shane steps back to give him space to launch another bomb.

1:22 -Seems like he's going to the body as a decoy, Floyd dressed down in defence.
1:16 So Shane loops a bomb over hand, Floyd knees buckle like a MF! See IMO most would have fallen.

Floyd tries to grab, had no c strength to, so he backs to the ropes as Shane throws 2 rights that miss the mark. Then to the body.

This shot and the one at 2:09 Shows/proves why Floyd has never been dropped. Just a standing 8 count when his glove scraped the canvas.


Floyd shook it off. IMO Shane's body language was "well...that was my best"
