There’s a civil and a separate criminal case against Sergey Kovalev, meaning that he has two legal proceedings to deal with.
Krusher only made one initial payment for $250K of the agreed $650K settlement figure to resolve the civil lawsuit, despite apparently earning $10m for the Canelo bout. He breached a written contract and is now being sued for much more… and fraud is now one of the claims being made against the Russian (and to be fair, they seem perfectly valid).

In terms of the criminal jury trial, I believe that has recently been pushed back twice (November 26th 2019 and January 6th 2020). I am not sure when (or if) this will actually be held.
I suspect the settlement agreement for the civil case (even though Krusher failed to fulfil it) may have resulted in the delay of the criminal jury trial (since the terms of the settlement agreement included a stipulation whereby the plaintiff was expected to waive her right to restitution in the criminal case).
