Le'Veon Bell was spotted in Pittsburgh at an L.A. Fitness on Tuesday playing basketball.
Despite the video, there was no indication Wednesday that Bell had visited the team's facility.
Bell has failed to sign his $14.5 million franchise tender while preserving his long-term health for a future lucrative contract.
On Wednesday night, Bell posted two messages on his Twitter account in upside-down text, saying in part that he's "not apologizing for what I believe is right for myself, family, and the rest of my peers, period."
