The Saints have lost their top wide receiver for the rest of the season.

Brandin Cooks, the first-round draft pick who is the leading wide receiver in New Orleans this year, is being placed on season-ending injured reserve, Field Yates of ESPN reports. Cooks was injured in Sunday’s loss to the Bengals.

Although the initial word on Cooks’s injury was that he had suffered a broken thumb that would force him to miss two to four weeks, apparently additional testing has revealed that the injury is more significant than previously believed. Yates reported that Cooks has a wrist injury.

Cooks ends his rookie year with 53 catches for 550 yards and three touchdowns, seven rushes for 73 yards and one touchdown, 10 punt returns for 35 yards and one kickoff return for 12 yards.
