GREEN BAY – Packers receiver Davante Adams will be in the rehab group Thursday after exiting Wednesday's practice with a calf injury, Head Coach Mike McCarthy confirmed during his Thursday pre-practice news conference.
Fellow receiver Randall Cobb also will be in the rehab group. The eighth-year veteran hasn't practiced since injuring his hamstring during last Thursday's padded practice.
With Geronimo Allison still in the concussion protocol, the Packers' three rookie draft picks – Marquez Valdes-Scantling, J'Mon Moore and Equanimeous St. Brown – will receive a bulk of the first-team reps during Thursday's practice and could have significant roles in Sunday's game against the Detroit Lions.
Valdes-Scantling stepped in for an injured Cobb during Sunday's 22-0 win over Buffalo, playing 54 offensive snaps and catching one pass for 38 yards.
"It's about those guys taking advantage of their opportunity," McCarthy said. "They're getting better. You're seeing it in practice. The opponent squad work is very important. We coach that in our young guy meetings. It's not about learning the plays of the game plan, but it's also about progressing with the opportunity to compete.
"Today is our padded work. We'll still do 9-on-7s and one-on-ones versus the defensive backs. It's all a part of developing your young players. This is why you do it. At some point in the season, your young players are going to play and our receiver position is potentially in that situation."
Depending on who's available at receiver, the Packers also have a deep backfield and tight-end corps to pull from. While Jimmy Graham didn't practice Wednesday, McCarthy said the team is just following a similar maintenance plan as last week.
Running back Ty Montgomery also has been a weapon for the offense in the passing game. He's caught 11 passes for 135 yards this season, including a 43-yarder Sunday against Buffalo.
