Port, I believe the date was April 30, 1986. The same crew wrestled in Amarillo the night before.
 
From Nick Roberts' journal, the April 29, 1986 show in Amarillo (and beside it the notes from the following night in Lubbock)...
 

 
As you can see, the lineup changed quite a bit from what had been advertised.
 
It appears this may have been the "final straw" (as you alluded to the many no-shows in another thread,) and thus the final World Class shows promoted by Mr. Roberts. There is a May 25 card listed, but no town and no numbers so I suspect that may have not happened. The next shows were mid-July with UWF talent (many of them former World Class talents -- Freebirds, Fantastics, Kamala)

OK, I think I got it figgered out.  The results show from Amarillo.  Next page says "Lubbock=Same as Amarillo"   BUT on this card Kerry subbed for Kevin in the first blood match against Gordy.  I remember Gordy already was wiping blood from his forehead (presumeably still bleeding from the previous nite in Amarillo) on the way to the ring.  And I have the photographic evidence.  

Kevin did have the shoulder injury as this was one week or so before the Parade of Champions at Texas Stadium that drew, what, 5,000 tops. Kevin was replaced in the six-man at Texas Stadium by Steve Simpson.

From Mr. Roberts' journal, this is the May 25, 1986 card. I was unsure if it ever took place since there are no notes as far as attendance and who the referee was (and, from looking at his other journals, that's unusual for him NOT to have that listed.)  
 
It does have Chris Adams against Rick Rude, so maybe this IS the last card with World Class talent promoted by Mr. Roberts. It's the only show listed between the April 30 Lubbock card and a July 14 El Paso card featuring UWF talent.

I used to call Nick monthly to see what the cards were for the month.  He'd usually call me back with the card line ups.  I remember this transition period because he stopped returning my calls and finally called out of the blue to tell me about the UWF card which I already knew about due to the TV advertisements which came from KVIH channel 12 (ABC affiliate) out of Lubbock.  Shortly after this time the KVII station from Amarillo  took over the eastern New Mexico area and we had no UWF TV for a couple months until somebody started carrying the syndicated UWF show.

Interesting side note.  The matches I recall from the first UWF card was......................
 
Sheepherders vs Fantastics      New Zealand bootcamp match (barbed wire, tables etc)  
 
Gordy and Roberts vs Watts and Terry Taylor
 
Koko Ware vs John Tatum  
 
Think Sting, Gilbert and Rick Steiner were on hand and it was held at the Coliseum instead of the Civic Center which I thought was odd as its probably about 5 times larger than the Civic center.

I didn't realize that was the first UWF card in Lubbock. I was at that card as well with my little brother. It was a great card.I loved the tag amtch between the Sheps and the fantastics. It was awesome.
I also remember the sutograph session that they had at the Coliseum before the card. I've still got  some of the autographs in my collection. Terry Taylor was one of my favorites of all time.
