Can someone help date Dallas Cowboys pants by Red Fox?

Hello,
I'm back once again hoping that one of my friends on Gameuseduniverse can help me with a Dallas Cowboys Jersey. Can anyone provide any info (player, authenticity, year, approx. value,...) on the attached #83 Fitzgerald Jersey? I know he was not a starter after researching rosters. Tag is Southland, numbers and name are screened on, not sewn.
As always, thank you!

I wanted to add that the sleeves on the Southland jersey are not screened but is within (colors) the jersey itself. Also, from my research, there was no #83 listed on the 1965, 66, 79 and 80 team photos. Wondering if this player did actually exist but just never made it to the line-up? Hope you can help with any info.

They only wore that style of jersey from 1974-1981. The only Fitzgerald I remember was center John Fitzgerald (#62). WR Golden Richards was the only one I remember wearing #83 during those years.

Thanks slats7! That helps me narrow down a few rosters. Like you said, John Fitzgerald wore #83 as well as Golden Richards and Clark. Judging on the size of JF, it definitely wasn't his @ 255lbs. My previous guess may be right (79-80) where I did not see a #83 in the line up. This, meaning he may have made the team but was cut before season started. Golden Richards ended his career in Dallas I believe in 1978, next Cowboy photo'd in #83 was Doug Donley in 1981.
In your opinion, the jersey's features look authentic?

I said that John Fitzgerald wore #62, not #83. It's possible that they had a camp body named Fitzgerald who wore that number in pre-season.

The jersey itself looks authentic.

I stand corrected, my bad. As always, thanks for valuable info and your opinion of the jersey.
