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.
