The Steelers and Cardinals are finalizing a trade involving Arizona offensive tackle Levi Brown, as first reported by Jason La Canfora of CBS Sports.
ProFootballTalk reports the deal is done pending a physical.
Brown has underperformed since re-signing with the Cardinals and could benefit in picking up the Steelers' system during their bye week.
The 0-4 Steelers are attempting to bolster an offensive line that has struggled to protect quarterback Ben Roethlisberger with tackles Mike Adams, Kelvin Beachum and Marcus Gilbert.
Pittsburgh may have to restructure its payroll to fit Brown's salary under their cap.
