Stewart, who is out of the lineup Sunday, may be a candidate for the DL due to a lower leg injury, Travis Sawchik of the Pittsburgh Tribune-Review reports.

EDGE Analysis

Stewart is dealing with both knee and ankle ailments, which have effectively cost him two straight starts. If he does end up on the DL, look for Erik Kratz to become the primary backstop, while Jacob Stallings could once again get the call from Triple-A.
