Jackson (illness) remained sidelined at practice Thursday, Jonas Shaffer of The Baltimore Sun reports.
Shaffer adds that the Ravens are hoping that the quarterback can bounce back from his non-COVID-19-related illness in time to practice Friday. Earlier Thursday, offensive coordinator Greg Roman told Shaffer that Jackson was "feeling better," but following back-to-back missed sessions, the signal-caller will likely need to get back on the field Friday for the Ravens to be more comfortable that he'll be ready to go Sunday against the Bears.
