Jackson (quadriceps) threw during the portion of Thursday's practice open to the media, Jeff Zrebiec of The Athletic reports.
Coach John Harbaugh told Zrebiec on Monday that the Ravens intend to take a "wait-and-see" approach with Jackson, who hurt his quad on a low hit during a Week 14 win at Buffalo. With some activity evident Tuesday, Jackson appears poised to match his 'limited' listing from Monday, at the very least. His level of participation will become clearer upon the release of Tuesday's injury report.
