The Steelers are expected to consider trade requests for Brown prior to the start of free agency, sources told NFL Network's Ian Rapoport.
Some general managers around the NFL believe it will take a first-round pick to acquire the star receiver, while one believes it will take multiple high picks, according to Rapoport.
The deadline for a trade would be the $2.5-million roster bonus Brown is due on the third day of the new league year. If he is dealt, Pittsburgh would save $1 million against the salary cap and create $15 million in cash savings.
The former All-Pro receiver was benched for the team's season finale after he skipped a team walk-through last Saturday. On Wednesday, head coach Mike Tomlin said the two haven't spoken since before Sunday's game, and Brown didn't attend Monday's team meetings.
Tomlin also said he's yet to receive a formal trade request from Brown.
