Saints add RB Patrick Cobbs

The Saints have added running back Patrick Cobbs to their roster, three days after running back Joique Bell left New Orleans' preseason opener with a knee injury. Cobbs, who starred in college at North Texas, has spent five seasons in the NFL, appearing in 54 games with Miami. Cobbs' agent, Lance Riddle, says his client signed a one-year contract and joined the Saints on Tuesday. Cobbs has made three NFL starts. His best season was 2008, when he carried 12 times for 88 yards and had 19 receptions for 275 yards. The Saints have said Bell has a strained posterior cruciate ligament and the timetable for his return is unclear.
