The Patriots traded a conditional draft pick to the Saints for return man Jalen Saunders.
Saunders, who also plays wide receiver, is entering his second season. The Jets drafted him out of Oklahoma in the fourth round last year. He saw limited action with the Jets and they released him after six games.
Saunders spent time on the practice squads of the Cardinals and Seahawks before the Saints signed him to their 53-man roster in November. He returned nine punts for 99 yards and three kickoffs for 139 yards, including one 99-yard effort, in five games for New Orleans.
The Patriots held joint practices with the Saints before their second exhibition game, allowing the coaching staff to get a closer look at Saunders.
He joins a receiving corps that has been depleted by injuries this preseason.
