When asked about his status for Saturday's game against the Ravens, Bell -- who suffered a hyperextended knee in Week 17 -- acknowledged "obviously, I'm taking it day-by-day," NFL.com reports. The report indicates that Bell was spotted Wednesday walking "with no discernible limp." Still, while the running back suggests that he is feeling "great" at this stage, he remains very iffy for this weekend's action, with the Steelers having added Ben Tate to bolster their backfield depth behind healthy options, Josh Harris and Dri Archer.
