JACKSON, Miss. (AP) -- Saints rookie Adrian Arrington has missed his second-straight practice with a sprained toe.
Head coach Sean Payton says the injury may be serious enough to sideline the former Michigan wide receiver for more than a week.
He's missed practice on Saturday and Sunday.
Arrington, who is 6-foot-3, 192 pounds, had been making a strong case for a roster spot since his selection in the seventh round of last spring's NFL draft.
He had two catches for 46 yards, including a 33-yarder, during the Saints' 24-10 preseason victory at Arizona last Thursday night.
Competition among New Orleans receivers has been fierce since the Saints opened training camp at Millsaps College on July 23.
