The Steelers officially released Olszewski on Saturday, Teresa Varley of the team's official website reports.
No surprise here, as Brooke Pryor of ESPN.com previously reported this transaction was expected. Olszewski's exit will presumably open up a roster spot for fellow pass catcher Diontae Johnson (hamstring) to be activated off IR ahead of Week 7. Olszewski was primarily used as a returner during his two games on the 53-man roster.
