GREEN BAY, Wis. -- After bringing in 27 players on a tryout basis for their rookie orientation camp last weekend, the Green Bay Packers did some roster shuffling Monday afternoon -- moves that included releasing defensive tackle Josh Boyd, who'd spent the past three seasons with the team.

In addition to signing second-round pick Jason Spriggs -- leaving only first-round pick Kenny Clark and third-round pick Kyler Fackrell unsigned from their seven-player draft class -- the Packers also signed tight end Casey Pierce, defensive tackle Demetris Anderson, running back Brandon Burks, fullback Alstevis Squirewell and guard Cory Tucker.

Pierce spent last season on the Detroit Lions' practice squad after going undrafted out of Kent State; Anderson, Burks, Squirewell and Tucker are tryout players who earned contracts with their showings during the team's two practices Friday and Saturday.

To make room on the 90-man roster, the Packers released Boyd, tackle Jeremy Vujnovich, defensive tackle William Campbell, tight end David Grinnage and wide receiver Dennis Parks.

Boyd, a fifth-round pick in 2013, played in 26 games in three seasons with the Packers but suffered a broken ankle in the second game of last season and spent the rest of the year on injured reserve.

Vujnovich spent all of the past two seasons on the Packers' practice squad.
