The report, filed with Cleveland police on Sunday, says that Kimberly West met with authorities at Cleveland Hopkins International Airport, where she had gone to fly to her father's house in New Jersey.
In the report, she says that Delonte West had accused her of cheating on him and that they had argument in which he grabbed her and took her wedding ring and purse.
Police said Monday the case remains under investigation and that no charges have been filed. WOIO-TV in Cleveland first reported the complaint.
Cavaliers coach Mike Brown says the team is aware of the report and is monitoring the situation. West's agent, Noah Croom, didn't immediately respond to a message seeking comment.
West has not appeared in any preseason games, and Brown has not decided whether West will be active for the season opener Tuesday against Boston. West was at the Cavs' practice Monday but was not made available to the media.
West, who has been treated in the past for bipolar disorder, twice left the team during training camp for personal reasons. He is also facing misdemeanor weapons possession charges stemming from a September arrest in Maryland.
