Pittsburgh Steelers head coach Mike Tomlin vowed Tuesday that disgruntled receiver Martavis Bryant is not available via trade. That doesn't mean he'll be available to the Steelers on Sunday, however.

Bryant told reporters Wednesday he was informed by the team he'll be inactive against the Detroit Lions due to "social media" outbursts, according to ESPN's Jeremy Fowler.

As a result, he was demoted to the scout team at practice, Fowler adds.

Bryant said Tuesday that if the Steelers "don't try to include me more and continue to do the same thing, then I want out, period." He also lashed out on social media, admonishing fellow receiver JuJu Smith-Schuster, who has gotten more attention in the offense.

The Steelers responded by stating they intend to keep the fourth-year pro, but it appears he won't avoid punishment.

Bryant said he's prepared for any fallback from his actions, according to Fowler.
