Shelly Sterling will seek a court order of protection for her, her lawyer and witnesses such as the doctors who evaluated Donald Sterling from harassment by her estranged husband and his lawyers, sources told ESPN.com on Wednesday.

Shelly Sterling and her attorneys will appear in a Los Angeles courtroom Thursday morning, sources said, to present evidence that Donald Sterling and his lawyers have threatened, intimidated and harassed witnesses who will be called in the probate court hearing July 7-10.

That hearing was scheduled after an emergency petition to the court last week by Shelly Sterling to evaluate the actions she took to sell the Los Angeles Clippers for a record $2 billion to former Microsoft CEO Steve Ballmer.
