WWE Hall of Famer Kevin Nash pulled out of the Raw 25th anniversary episode for next week, citing difficulties in air travel following his knee replacement. Nash underwent a knee replacement last month but was still booked to appear on the show until now.

“Was so looking forward to being a part of RAW 25,” Nash wrote on Twitter. “It’s nearly impossible to travel on our down sized airlines healthy. With a total knee replacement it would be self inflicted torture. See ya everyone at Mania.”

Nash was one of the first three WWE Legends to be appearing on Raw 25 along with The Undertaker and Shawn Michaels. Nash’s former tag team partner and fellow Kliq member Scott Hall is still scheduled to appear.
