For a moment, Han experiences the resistance of his body falling one way and his shackled left wrist being pulled on the other. In the next moment, that resistance caused by the bones in his wrist suddenly falters. Several bones give way and the pain is so explosive that Han can't even cry out or scream. He just chokes, reflexively, on the agony.

Han's impressively fast right-hand collects a tight handful of the gold mesh of Jim's Starfleet uniform. With all his strength and bodyweight as leverage, Solo jerks downward as hard as he can. Where cotton material would have just ripped under the strain, Jim's uniform actually contributes to Han's success in pulling him down.

Refusing to let go, even as Han has completely pulled him into the dirt, the Scoundrel starts using those natural advantages he has over Jim to keep him down; even as he struggles to get free. It makes him howl in pain to do it, but Han reaches his limp wristed hand down into the dirt and he throws what he grip into Kirk's eyes.
