Why hasn’t Mark Henry been on WWE TV?

The Wrestling Observer Newsletter is reporting that Mark Henry is still under contract to WWE, and despite him being open about wanting to retire in the near future, he is not yet retired.Henry is not being used on TV because the WWE is in a  rebuilding phaseright now, and officials are concentrating on new talent and building new stars right now, so creative hasn’t had anything for Henry.

This could also be the reason why talents like Kane and Big Show haven’t been seen on TV in awhile despite them working live events.
