PITTSBURGH -- An inconclusive X-ray left Steelers quarterback Ben Roethlisberger on the sideline for most of the second half of Sunday's 24-21 loss in Oakland.
Coach Mike Tomlin said Tuesday that the X-ray for Roethlisberger's rib injury was "not clearly readable" during the halftime evaluation, possibly due to dated equipment.
Further tests in Pittsburgh showed multiple rib contusions, though Roethlisberger is expected to play Sunday against the New England Patriots.
This is the latest news in a busy time for the reeling Steelers, who are also trying out kickers in light of Chris Boswell's struggles.
