Baltimore worked out Niese (leg) on Tuesday, Jeff Zrebiec of The Athletic reports.
Niese was placed on the Lions' IR and subsequently waived with an injury settlement after sustaining a leg injury during their preseason finale, but he's now apparently healthy again. With rookie first-rounder Vega Ioane expected to miss time with a sprained MCL, the Ravens seem to be looking to potentially add some depth on the interior of the offensive line.
