FOXBORO (AP) - The New England Patriots announced the signings Thursday of six draft picks, including defensive lineman Ron Brace and offensive tackle Sebastian Vollmer, two of the team's four second-round selections.

The 6-foot-3, 330-pound Brace, from Boston College, was the 40th overall selection in the 2009 draft. He could provide insurance if the Patriots are unable to re-sign nose tackle Vince Wilfork, whose contract expires after the upcoming season.

Vollmer (6-8, 315), the 58th overall pick, grew up in Germany and didn't play football until he was 14. He started out as a tight end at Houston and wound up starting his last 25 college games at tackle.

The Patriots also announced the signings of third-round pick Brandon Tate, a wide receiver from North Carolina who is recovering from a knee injury; offensive lineman George Bussey, a fifth-round pick from Louisville; defensive lineman Myron Pryor, a sixth-round pick from Kentucky; and seventh-round pick Julian Edelman, who played quarterback at Kent State but is projected as a wide receiver by the Patriots.

Terms of the deals were not announced. Safety Patrick Chung, from Oregon, the first of the Patriots four second-round picks, remains unsigned. The Patriots previously announced the signing of cornerback Darius Butler, from Connecticut, the 41st overall selection.

Training camp in Foxboro is scheduled to begin July 30.
