Went to wrestlingdata.com to check that out, and apparently his last wrestling match prior to this year was in 2004. But here's the thing: it was in TNA. (7/14/04, to be precise: Shamrock/Jarrett/Onyx/Hernandez/Chad Collyer lost to Dusty/Zbyszko/Konnan/Road Dogg/R-Truth in a guitar on a pole match. Because Russo.)
Also ran across another odd match he had in '04: against Sylvester Terkay on UPW's 5th anniversary show in Anaheim, which also had the Outsiders putting over Christopher Daniel and Tom Howard. God damn, I love wrestling.
