Adams will miss "multiple weeks" of the preseason after having surgery Tuesday for a foot injury, coach Mike McCarthy said. The third-round pick from Auburn was expected to compete for snaps on the defensive line. He dropped out of camp after the second day of practice and has yet to work in pads.
He joins Biegel, a fourth-round pick from Wisconsin, on the sideline. Biegel underwent foot surgery in May shortly after rookie camp and was not ready for the start of training camp. The outside linebacker was placed on the physically unable to perform list. McCarthy said Biegel could return in "a few weeks."
Because Adams practiced the first two days in camp, he is not eligible for the PUP list.
"I don't think it's time for concern. It's the unfortunate part of our game," McCarthy said. "When it happens to young guys, these practices are so critical for their development, especially in Year 1, not only learning what to do and how to do it but just how we practice and everything that goes into it. It's just unfortunate."
The Packers finished 22nd in defense last season and were second-to-last in the league in passing yards allowed.
