That would be a category of boxer. Basically it is meant as a description of a lower level fighter but, sometimes the media will use the reference loosely and christened even a rated commodity as a "Journeyman". You might be able to get better depth on this reply if we use names of past and present boxers. It is a nice study, time applied.. Perhaps "Rocky" in the Rocky series would be a legitimate Journeyman boxer.
Journeymen
In a union shop, there are three levels of workers: apprentices, who are being trained in their trade; journeymen, who are proficient; and master tradesmen, who train apprentices and advise journeymen. I also found out journeymen were once called jacks.

the Willet Family has written: 'The rowing journeymen'
Journeymen were workers who had been through apprenticeship but not yet finished a masterwork and achieved the status of master. It was not uncommon for them to move from one town or city to another, working with a number of masters to learn what they could from each. They were not called journeymen because of travelling, but from a French word, journee, implying that they could charge a fee for each day's work.
last year most of my journeymen netted over $145,000
The area where a boxing fight is held is called a boxing ring.
Sheetmetal Journeymen payscale is $20.85.
