Add unemployment to Chad Johnson's list of problems -- the Miami Dolphins have reportedly cut their star wide receiver ... 24 hours after his arrest for domestic violence.

Sources close to the veteran player tell TMZ ... he had a meeting with Dolphins head coach Joe Philbin about an hour ago. Must not have gone well -- FOX Sports' Jay Glazer is reporting the team dropped Johnson.

As we previously reported, Johnson was arrested Saturday night and booked for domestic violence ... after allegedly head-butting his wife, "Basketball Wives" star Evelyn Lozada.

He spent the night in jail and was released on $2,500 bond today.
