The Pittsburgh Steelers front office has officially adjusted the defensive depth chart in a pair of moves that shift the outlook for the remainder of the season. The team has placed Sebastian Joseph-Day on the Reserve/Injured list, a blow to the defensive line rotation that will now require increased production from depth pieces like Dean Lowry. Additionally, the organization has opted to release safety Rayshawn Jenkins, creating flexibility within the secondary as the team looks to solidify its final roster construction.
