The Falcons knew they were going to need some cornerback depth, with Desmond Trufant out for the year with a torn pectoral muscle.

They found it Tuesday, signing former third-round pick Blidi Wreh-Wilson and putting Trufant on injured reserve.

They also waived spare punter Matt Wile and signed center Trevor Robinson, who has spent time with the Bengals and Chargers.

Wreh-Wilson spent his first three years with the Titans, but was among their first cuts this year. He was a regular starter there in 2014, but other than a few workouts, hasn’t surfaced since being released in late August.

Trufant will need surgery to repair the pectoral injury. They’ve already picked up the fifth-year option on the 2013 first-rounder’s rookie deal.
