According to an interview by the SunSport WrestleCast, Mick Foley stated that he recently turned down an offer to turn heel in TNA.

“This is breaking news, and maybe I’ll get in trouble for this, but TNA had discussed me doing a big heel turn. But with this anti-bullying campaign we’re doing and coming off an award for reasonableness I was given by Jon Stewart, it just didn’t seem right. To be hitting people with my reasonableness award on TV would be funny, I could have done a couple of weeks of good television. But in the bigger picture — and I think TNA has got to start looking at the bigger picture more often — I could be a lot more effective as somebody who goes out there and talks about serious issues.”
