Tank Tyler, a third-round pick of the Chiefs in 2007, is the most experienced player of the group to visit Foxboro. At 6-2, 325 pounds, Tyler has played in 43 career games, making 19 starts. After being traded to the Panthers in October 2009, Tyler was waived by Carolina during final cuts this preseason.

An undrafted free agent this season out of Catawba, Julian Hartsell spent training camp with the Titans. At 6-3, 291 pounds, Hartsell can also play defensive end, recording nine career sacks in college.

The team also worked out 6-2, 307-pound Sealver Siliga, an undrafted free agent out of Utah who spent training camp with the 49ers.

In addition to Wright and Haynesworth, the Patriots also have Vince Wilfork, Kyle Love, and Landon Cohen on the roster at the position, but do not have a defensive tackle on their practice squad. Both Hartsell and Siliga are practice squad eligible.
