Former Chargers general manager A.J. Smith died Sunday at the age of 75, his family announced.

Smith had been battling prostate cancer for the past seven years, his family said in the announcement, which was released by the Falcons. Smith's son, Kyle, is the Atlanta Falcons' assistant general manager.

Free agent outside linebacker Bud Dupree signed with the Los Angeles Chargers, the team announced Saturday.

Dupree, 31, had a career renaissance last year, notching 6.5 sacks and 39 tackles with eight tackles for loss and eight quarterback hits for the Atlanta Falcons. He quickly emerged as the team's top stand-up edge rusher in Atlanta's defensive scheme, often playing on many vital snaps.

The Los Angeles Chargers have agreed to a contract with D.J. Chark, Jr., a source has confirmed.

Chark, a veteran of six NFL seasons, brings experience to a young wide receiver room.

Prior to the agreement, the Chargers had no receiver with more than three years in the NFL or a season with over 800 yards.
