An AP report says that umpire Brian Runge was dismissed due to a drug violation:

The two people said Runge failed at least one drug test, then reached an agreement so he could remain on the umpire roster. When he failed to comply with those terms, he was released.

The people spoke on condition of anonymity because MLB didn’t publicly say why Runge was gone.

It could not be independently determined by the AP what drug was involved.

Joe West, president of the World Umpires Association – the union representing umps – declined comment Tuesday.

The AP was unable to contact Runge through the union or other umpires.

We’ll see how this story develops.
