Throw-in violation - Official's mistake

[gogumakilla]

Hi everyone, new here. Been reading this forum a lot and finally decide to post. Great stuff, especially while I'm at work . Here's my scenario:

A1 gets an OOB spot throw-in along the end line. Timeout is called and after the timeout, A1 becomes the thrower. The official mistakenly tells the thrower he can run the baseline. The thrower does run the baseline. The partner official (unaware that his partner said he can run) blows his whistle and signals for the violation.

What do you do?
