10:23 AM PT — The Seahawks just announced they’ve cut Trevone Boykin.
Trevone Boykin is being investigated by police for allegedly breaking his girlfriend’s jaw … TMZ Sports has learned.
Cops in Mansfield, Texas tell us they are investigating Boykin, 24, for allegedly severely injuring his longtime girlfriend, Shabrika Bailey, during a physical altercation last week.
The Seahawks QB and Bailey have dated for years.
Bailey talked to WFAA in Texas … telling them her and Boykin were arguing over a text message when he started to choke her. She says she lost consciousness … before waking up in a pool of her blood.
She says Boykin eventually took her to a hospital … but fled the scene when the hospital staff questioned her about the injuries.
Law enforcement sources tell us they expect Boykin to be charged with aggravated assault — a felony. however, there is not currently a warrant out for his arrest.
This isn’t Boykin’s first time in trouble with the law … he was charged with assault after getting in a bar fight in 2015 — 2 days before he was supposed to play in the Alamo Bowl.
He ended up getting a year probation in that case.
We’ve reached out to Boykin’s rep … so far, no word back.
