Kevin Nash posted the following on his Twitter account tonight:
Made up my mind, packing my wresteling gear. Someones getting a beat down in Tampa tomorrow night on Raw.
As noted earlier, Triple H was being advertised for tomorrow's RAW as recently as yesterday, but is no longer listed in the advertising. The arena is currently advertising CM Punk defending his WWE title against John Cena and Alberto Del Rio and a 41 man cross-brand Battle Royal for the show, both of which are likely dark matches.
Nash also set this pic as his Twitter page background:
