Shocking new details in the Derrius Guice domestic violence case ... the NFL player's GF told cops he choked her unconscious during a March incident and when she came to, he was crying next to her.
It's all in new court documents obtained by TMZ Sports ... which spell out the allegations from 3 separate incidents allegedly involving the former Washington Football Team running back, beginning on Valentine's Day.
INCIDENT #1 -- Feb. 14, 2020
Guice's girlfriend told cops he "pushed her to the ground in his bedroom bathroom, causing injury to her left thumbnail where she caught her fall."
The woman says the nail eventually fell off due to a "popped blood vessel."
INCIDENT #2 -- March 13, 2020
Guice's GF told cops he "strangled her until she was unconscious by putting his hands around her neck and applying pressure."
The woman says when she regained consciousness, Guice was "crying and tapping her."
She told cops Guice had also pushed her and pulled her hair more than once that same day.
The woman says she left the house to catch a flight and didn't look in the mirror until she was at the airport. That's when she realized she was badly bruised and took photos of her injuries, which she submitted to police.
INCIDENT #3 -- April 17, 2020
The woman says Guice pushed her to the ground outside of his Ashburn, Virginia home causing injuries to her body, which she again photographed.
She claims Guice also thew her cell phone into the street, causing it to shatter.
As we previously reported, Guice was arrested on Friday and hit with multiple serious charges including assault and battery, felony strangulation and destruction of property.
If convicted on the felony, the faces up to 5 years in prison.
He was released on bond -- and cut by the Washington Football Team later that day.
Guice was a top running back at LSU during his college days and was selected in the 2nd-round of the 2018 NFL Draft.
He flashed huge potential but was hampered by injuries.
After he was cut, no teams picked him up from the waiver wire -- begging the question ... is this a wrap for Guice's NFL career?
