Darth and TA is called off.
DA and TA seems to still be on though, TA is getting the trip paid from what I understand, and that was his condition to do the fight.
ET and Guy Grundy? Looks to be off.
Big Business and Baroni? Very unlikely...

240 or Bust vs Cicherillo or Kamali? I don't see that fight happen TBH.
McCrackhead vs VP? You never know, they seem to be cool with each other these days, but will prolly get in the ring for a fight if they ever meet up, just for the hell of it (the only two guys who seem willing to walk the walk IMO).
VP vs Mower? Never. Mower is stupid, but he knows he would risk permanent damage if he would get in the ring with VP
I know there are more, but these are the ones on the top of my head.
YIP
