The Detroit Lions were off from practice on Sunday, but the team still made a change to the roster. The Lions signed cornerback Colby Richardson to the 90-man roster.
Richardson is an undrafted rookie from LSU, where he transferred from McNeese State. He originally signed with the Carolina Panthers after the draft but was waived earlier this summer. The 25-year-old is a 6-foot-1 outside CB and will fill the roster void from the Lions waiving CB Tae Hayes on Saturday.
Richardson’s roster spot came available when the team released offensive lineman Ross Pierschbacher with an injury settlement. Pierschbacher had been the team’s primary backup center. He suffered an injury in the preseason opener against the Giants and did not return.
