I may be misremembering so someone can correct me if I’m wrong but I recall Bischoff saying (as far as he can be trusted as a reliable narrator) that Hogan didn’t wanna actually wrestle when he was with TNA as his body was already getting bad by that point with his knees/hips/back.

Checking CM, looks like Hogan only ever worked 5 matches total during the years he worked there. 4 tag matches, and 1 singles against Sting.
