Ex-NBA player Rick Brunson is being sued over an alleged violent sexual incident with an Illinois masseuse ... despite the fact he was found not guilty last year, TMZ Sports has learned.
Brunson's case made headlines in 2014 when he was arrested for sexual assault and other charges ... after a masseuse claimed he tried to force her to perform oral sex at the end of a massage.
Long story short ... the woman claimed Brunson pulled down her shirt, grabbed her boobs and tried to force her head into his crotch.
