The Ravens secondary got even thinner when it announced cornerback Jimmy Smith had surgery to repair a sports hernia this week, and will be out for Baltimore's Week 11 game at Pittsburgh, and beyond.

Smith was thrust into the starting lineup after Week 6 when CB LarDarius Webb tore his ACL in a win over the Dallas Cowboys.

In response to Smith's absence, they signed Chris Johnson to their active roster. Johnson last played for the Oakland Raiders in 2011, requesting to be released this past offseason after a family tragedy.

Corey Graham will start opposite Cary Williams at cornerback in Week 11. Chykie Brown will be the nickel back.

It's up in the air how the Steelers' passing offense will handle the loss of Ben Roethlisberger and the possible (likely) absence of Antonio Brown, but clearly, the Ravens pass defense has been thinned out quite a bit. While that likely doesn't balance out the loss of Roethlisberger and Brown, the Steelers still may be able to attack Baltimore's cornerbacks.
