The Saints signed Cooks to the practice squad Thursday, John Sigler of SaintsWire reports.
Cooks was cut from the Eagles' practice squad Sept. 8 and had been a free agent since before joining the Saints' ranks Thursday. With injuries to Devaughn Vele (shoulder) and Dante Pettis (illness), Cooks is a prime candidate for elevation to the active roster ahead of Sunday's game against the Jets.
