Raiders top draft pick CB D.J. Hayden hospitalized with stomach injury

Oakland Raiders first-round draft pick cornerback D.J. Hayden will be out until at least training camp with a stomach injury.

Coach Dennis Allen said Tuesday he expects Hayden will be healthy when training camp starts in late July.

Allen said the team can't rule out whether this injury is related to the one that nearly killed Hayden last year. Hayden tore a blood vessel off of his heart following an on-field collision with a college teammate at practice at Houston last November.

Hayden overcame that injury to be taken 12th overall in April's draft. The team said doctors had cleared Hayden and he was at no further risk of injury.

Allen wouldn't go into details about the symptoms but said they first appeared last week. Hayden is in the hospital.
