WWE Superstar Christian is scheduled to return at TNA's Bound For Glory pay-per-view to induct Sting into the TNA Hall of Fame.
Christian working Bound For Glory was the second part of the deal made with WWE to allow Ric Flair to work WWE's Hall of Fame earlier this year. There was a push on the TNA side to get Ric Flair to induct Sting but that likely won't happen because of the lawsuit against WWE where Flair is named.
Flair's non-compete with TNA ends on September 6th as it was a 120-day non-compete. Even if there wasn't an ongoing lawsuit where he was named, Flair still could not have worked the 1000th RAW last month. With that lawsuit still up in the air, WWE is afraid to make any direct moves as far as contacting Flair and bringing him back.
There's a feeling that Flair and Matt Morgan would both be in WWE right now if that lawsuit wasn't still going on.
