The night Johnny Manziel allegedly hit his girlfriend, Colleen Crowley ... one of her Dallas neighbors called 911 to report hearing Colleen's screams.
TMZ Sports obtained the 911 call the woman made, and she calmly says she went outside when she heard Colleen in distress. She says Colleen said her boyfriend had "beat her up."
The neighbor said Colleen didn't want her to call 911, but added, "I think I did the right thing." She says Colleen didn't want to come up to their apartment, so the woman's husband sat with her until police arrived.
