The Detroit Lions made three roster moves over the last 24 hours, signing rookie cornerback Colby Richardson, waiving cornerback Tae Hayes, and releasing interior offensive lineman Ross Pierschbacher with an injury settlement.
Pierschbacher, who had been one of the Lions' top reserve center options throughout camp, started Detroit’s preseason Game 1 against the Giants, as the team rested veterans Frank Ragnow and Graham Glasgow. Pierschbacher played on just nine offensive snaps before suffering an undisclosed injury and being forced from action. He was replaced by UDFA Brad Cecil for the remainder of the game.
