On Wednesday, the running back posted two tweets with the font purposely framed upside down.
"Just about everybody has an opinion on my life and worried about what I'm doing ... Don't judge me off my decisions because maybe this isn't what you'd do ... But most people don't take the time to simply read between the lines ... And that's clearly on them," Bell wrote.
"I'm not apologizing for what I believe is right for myself, family, and the rest of my peers, period ... Also if you're really finding the time to figure out what I'm saying, you've proved my point."
It was reported earlier Wednesday that Bell is contemplating not returning to the Steelers before the Nov. 13 franchise tag deadline. Bell tweeted that he was leaving Miami on Monday, where he had been working out away from the team.
