Meanwhile, the ex-girlfriend of Foster, Elissa Ennis told Good Morning America she felt she had "another slap in the face" when she discovered he would be signed by the Redskins. Ennis said they were both working on their relationship.
Ennis, now claiming she lied during that earlier trial, says she did so because she loved Foster. After Foster was arrested on charges of felony domestic violence stemming from a February incident at his home in Los Gatos, California, the 49ers told Foster that any future legal issues would likely result in his release. She is also claiming that 49ers representatives tried to discredit her to police during Foster's November 24 arrest.
Reuben Foster's accuser spoke to ABC News and said the Redskins" hiring of the linebacker was "slap in the face'.
Ennis alleged she sustained a concussion from the slap from the 6ft tall, 16-stone linebacker.
"When he got signed, I was like, I can't believe somebody picked him up", Ennis told GMA.
"Because I loved him, and love will have you doin' things that's not in your best interests", Ennis said when asked why she recanted.
"We both were seein" therapists and stuff, tryin' to work on our relationship", she said.
A criminal report affidavit obtained by ABC News said that Foster allegedly slapped Ennis's "phone out of her hand, pushed her in the chest area and slapped her with an open hand on the right side of her face".
Officers observed an inch-long scratch on the side of Ennis's left collarbone and took Foster into custody, police said.
Foster had gotten physical with her three times before, she said.
She alleged that it was one of many attacks he subjected her to during their relationship. He then allegedly dragged her down the stairs, punched her in the face and kicked her, Ennis said.
In October, she said another incident prompted the neighbors to phone the police. "I did what I had to do for the person I love". "I thought that he would change, anybody in my position would do the same thing". She told GMA she lied when she recanted, saying she did so out of love. Foster did plead no contest to a weapons charge, which had been reduced to a misdemeanor, and he was sentenced to 232 hours of community service and was placed on two years of probation and barred from possessing any guns or ammunition. The team dropped him afterwards.
'We care a lot about Reuben and I can tell you that it was a situation where we laid down some very specific ground rules for Reuben, as we do for all of the players.
'Unfortunately what transpired, this isn't a comment on what happened there because that would be mere speculation, it's more of a comment on him not living up to what we communicated to him. Additionally, Ennis admitted at the time that she previously served jail time in 2011 for falsely accusing another ex-boyfriend of domestic violence after he broke up with her.
Speaking on Fox Sports, Sharpe questioned why the Redskins were "willing to give Reuben Foster an opportunity but they are not willing to bring Colin Kaepernick in and give him a workout".
Doug Williams, senior vice president for player personnel, infuriated the industry the next day when, in a radio interview, he described the allegations against Foster as "small potatoes" compared to people in 'high, high, high, high places that have done far worse'.
Foster will not be able to practice or attend games while the National Football League investigates.
The 49ers declined comment to "Good Morning America".
In January this year, Foster was arrested in Tuscaloosa, Alabama, for marijuana possession.
