With his teammates getting their first exposure to Dom Capers’ complicated defense, Damarious Randall was limited to mental reps on the first day of the Green Bay Packers’ rookie orientation camp.

Randall, the team’s first-round pick, was sidelined on Friday by what he called a “minor” ankle injury

“He’ll be ready to go probably next week,” coach Mike McCarthy said.

Randall said he sustained the injury before arriving in Green Bay.

“I’m just going to do whatever the coaching staff wants me to do,” Randall said. “Whenever they feel like I’m ready, that’s what I’m going to do.”

For what it’s worth — and, trust us, it’s not worth much — the Packers lined up with first-year players Kyle Sebetic and Tay Glover-Wright with the first unit. Second-round pick Quinten Rollins was the nickel defender. Rollins and undrafted rookies LaDarius Gunter and Bernard Blake shared the second-unit reps. Rollins had a pick-six on pass from Brett Hundley.
