The Patriots have signed undrafted free agent Rashad Anthony White, a nose tackle out of Michigan State.
White was previously with the Pittsburgh Steelers, but was placed on injured reserve before being waived off the injured reserve list earlier this offseason. The nature of the injury that landed him on injured reserve is unknown.
The 6-foot-2, 330-pounder out of Battle Creek, Mich., started 12 games for the Spartans at nose tackle during his final college season, totaling 23 stops.
The Patriots now have 90 players on their roster, the maximum allowable limit entering training camp.
