ALAMEDA Raiders first-round draft pick D.J. Hayden has been released from a hospital after surgery to remove scar tissue from his abdominal region.
The team said Wednesday that the cornerback is home resting after the operation late last week. He is not expected back on the field until training camp in late July.
Hayden had surgery in November to repair a tear of the inferior vena cava, the large vein that carries blood from the lower half of the body to the heart. He was hurt in a practice collision at the University of Houston, and doctors had to cut through his sternum to save him.
Raiders doctors cleared Hayden, and the team drafted him 12th overall last month.
Broncos Denver signed free-agent cornerback Quentin Jammer after failing to land Charles Woodson, who signed with the Raiders.
Jammer, entering his 12th season, is the third longtime San Diego Charger to join the rival Broncos this offseason, following linebacker Shaun Phillips and guard Louis Vasquez.
Patriots Tight end Rob Gronkowski will have back surgery on a disc in mid-June, a source said.
The surgery would sideline Gronkowski for the rest of offseason training activities, but he could return for training camp.
Texans Running back Arian Foster, who strained his right calf Tuesday, won't return to the practice field until training camp, coach Gary Kubiak said.
Tests revealed no further damage, but the strain will keep Foster on crutches for at least a couple of days.
Saints Wide receiver Joe Morgan is free on bond after being arrested Saturday in Gretna, La., on charges of driving while intoxicated and driving without a license.
An arrest report said Morgan's blood-alcohol content registered at 0.218 percent, more than twice the 0.08 percent legal limit.
