From the DMN blog:
Wide receiver Isaiah Stanback will undergo surgery to repair a meniscus tear in his right knee.
Stanback suffered the injury in Tuesday's workout at Standridge Stadium but attempted to practice Wednesday without much success.
He is expected to be ready for training camp that starts on July 28.
Stanback has been troubled by injury since the Cowboys took him in the fourth round in 2007. He has had shoulder surgeries in each of the last two off-seasons after suffering a foot injury as a senior at Washington.
Stanback is competing for one of the final wide receiver spots and his absence will put him behind entering camp.
