Allen Park — The Detroit Lions made a few tweaks at the back end of the roster, bringing in a new cornerback, wide receiver and center the past couple of days.
Following Friday's preseason game, the Lions waived cornerback Tae Haynes, signing undrafted rookie corner Colby Richardson to fill the roster spot. Additionally, the team is adding center Alex Mollette to replace Ross Pierschbacher, who was waived/injured after leaving Friday's game in the first half.
Finally, the team waived/injured receiver Trey Quinn, re-signing Avery Davis, who had been waived last week.
Richardson, who spent last year with LSU as a graduate transfer, spent the previous five at McNeese State.
