The woman who claims she was attacked by NFL star Reuben Foster says reps from the 49ers tried to undermine her credibility with police during the investigation ... telling cops she had lied about domestic violence in the past.
Elissa Ennis appeared on "Good Morning America" Thursday where she accused Foster of roughing her up on 3 separate occasions ... including the Nov. 24 incident at a team hotel in Tampa, Florida.
As we previously reported, Ennis called 911 and told the operator Foster had slapped her and roughed her up during a dispute.
