It was initially reported that Brown was refusing to meet with team ownership, but that Rooney hopes to clear the air between the two parties.
Brown's future with the organization has been in question ever since he was benched for the regular-season finale after skipping practice. His discontent reportedly began over a dispute with quarterback Ben Roethlisberger.
The receiver then tweeted out a video on Tuesday with a caption that thanked SteelerNation and stated it's "time to move on."
The seven-time Pro Bowler remains under contract for the next three years and carries a cap hit of more than $22 million for 2019. Trading Brown by March 17 would leave the Steelers with $21.12 million in dead cap space, and that number would rise to $23.62 million if he's dealt afterward due to a $2.5-million roster bonus, according to ESPN's Field Yates.
The Steelers have said they'll consider trade offers for Brown, but that they won't release him.
