Valdes-Scantling worked out with the Chargers earlier Tuesday and now signs with the team’s practice squad. The 31-year-old spent the offseason with the Cowboys and has been a journeyman since his first four seasons with the Packers, also spending time with the Chiefs, Bills, Saints, 49ers, and Steelers over his career. The Chargers add Valdes-Scantling as depth with Ladd McConkey dealing with a rib injury and KeAndre Lambert-Smith (hamstring) heading to injured reserve.
