A woman, who is identified as the mother of the alleged victim, tells a dispatcher that McDonald is drunk during a 911 call about 3:41 a.m. PDT Monday.
McDonald was later arrested at a San Jose, California, home on suspicion of assaulting a woman who was holding the couple's baby.
The caller says she wasn't at the home but that her daughter told her to call police, according to the recording.
Later in the day, the Chicago Bears released McDonald.
The arrest follows a pattern of similar incidents.
McDonald's agent, Tom Condon, has not returned multiple calls seeking comment.Suggest a correction
