Mike Tomlin said during his press conference on Tuesday that guard Ramon Foster had been placed in the concussion protocol.
Foster reported to the South side facility on Monday complaining of concussion like symptoms before being evaluated and placed in the program.
Tomlin was not aware of how far along Foster was in the program and did not have an update on him.
If Foster isn't able to to on Monday, then second year guard BJ Finney would make his third start of the season. Finney replaced Foster against the Ravens, and Chiefs during the first half of the year.
