Lamb (leg) took part in practice Wednesday, Jon Machota of The Athletic reports.
Lamb's participation at the beginning of training camp confirms he's moved past the minor leg injury that caused him to miss a practice or two in June. The fourth-year wideout is locked in as Dak Prescott's favorite target, albeit with a bit more competition for the quarterback's attention after the Cowboys traded for Brandin Cooks and have a healthier version of Michael Gallup. Of course, Dallas also lost tight end Dalton Schultz this offseason, and there's room for the 24-year-old Lamb to command an even larger target share if he continues improving the way he did between his second and third NFL seasons.
