Three defense experts were questioned outside of the jury in the Karen Read trial in Dedham Superior Court. 

The prosecution wants to stop the witnesses from testifying for the defense over alleged disclosure rule violations. 

One is a crash reconstruction expert hired by the FBI who would testify that John O'Keefe's injuries could not be caused by Read's SUV as alleged by prosecutors. 

Another expert is a retired emergency room doctor who said in court that injuries to O'Keefe's arm were likely caused by a large dog. 

The judge will rule on the matters tomorrow.
