Ex-Minnesota Vikings receiver Cayleb Jones just cut a deal in court in his domestic violence case -- but he's still facing serious jail time ... TMZ Sports has learned.
The 25-year-old was facing 3 pretty serious charges -- including felony theft by temporary control -- after he allegedly beat the crap out of his girlfriend at a Minnesota hotel back in August.
Officials say the 6'3", 209 pound WR roughed up his GF and when she tried to escape in an elevator to call 911 ... Jones intercepted her, stole her phone and fled before cops arrived.
Cayleb was in court Tuesday to face the charges ... but we're told he cut a deal -- and instead, only pled guilty to interference with an emergency call -- a gross misdemeanor.
In exchange, we're told his two other charges will be dismissed.
Cayleb -- who's already served 5 days of jail time -- still faces up to a year in jail and a $3,000 fine when he returns to court for his sentencing hearing in April. It's unlikely he'll be ordered to serve more jail time unless the judge really wants to throw the book at him.
It's been a rough year for the WR -- as we previously reported, Cayleb tried to restrain his brother, Buffalo Bills WR Zay Jones, after he allegedly tried to jump from a 30th story window in an L.A. building last spring.
Cayleb -- who's yet to play in an NFL game -- was cut by the Vikings in September ... and remains a free agent.
