There’s suddenly a left tackle arms race in the AFC North.

After the Ravens made a move last night to get Eugene Monroe off the Jaguars, the Steelers are trying to keep pace.

A league source tells PFT that the Cardinals have agreed to a deal that will send tackle Levi Brown to Pittsburgh. Pending a physical, the trade will happen.

Jason La Canfora of CBS previously has reported that the two teams were “hammering out” a trade.

The Steelers have clearly been dissatisfied with their tackle play all year, rotating Kelvin Beachum in for both Mike Adams and Marcus Gilbert.

Cardinals coach Bruce Arians referred to Brown as an “elite” left tackle this offseason, but he must not feel that same way after a month of regular-season games.
