Armstead declares for draft but can't participate in Pro Day

Former USC defensive tackle Armond Armstead has declared for the NFL draft but was not allowed to work out at the school’s Pro Day on Wednesday, he said in an interview during the event on USC’s campus.

He plans to hold a private workout at a to-be-determined location on April 9.

Armstead, who did not play for the Trojans last season because of an unspecified medical condition, said he was informed by the school Tuesday night that he would not be able to participate based on the word of university attorneys.

Previously, USC athletic director Pat Haden had told him he’d be permitted to work out in front of NFL officials in advance of next month’s NFL draft.

Armstead had a year of college eligibility left before he signed with an agent this offseason. He initially planned to play out the year wherever his brother, high-school senior Arik, chose as his college destination.

But Arik Armstead signed with Oregon, and Armstead wasn’t allowed to transfer within the Pac-12 because of normal intra-conference regulations. So he decided to declare for the NFL draft after exploring other options.

After the 2010 season, Armstead received a second-round draft grade back from the NFL, he said. But he chose to return to school for his senior season with the hope of developing into a first-rounder. The following March, he was hospitalized with chest pain for five days and was never again cleared by the university for athletic competition.

“Of course I was upset that I couldn’t play,” he said on Wednesday. “It’s no ill will toward anyone, but I was obviously upset with the situation, not upset with anyone.”

Armstead weighed in at 6-5 and 285 pounds during Pro Day, appearing considerably lighter than he had during various appearances at USC’s practices last season.
