The Facts: Campanaro suffered a hamstring injury in Sunday's game against the Bengals and will not return.

Diehards Line: As CBSSport.com notes, the Ravens are also evaluating Torrey Smith for a concussion. With the team's top two tight ends sidelined and two receivers suffering injuries in the second half, the depth of Joe Flacco's pass-catching corps is being severely tested in the Week 8 battle. Campanaro had three catches and a team-high 40 receiving yards at the time of his injury.
