The Patriots have signed free agent offensive lineman Matt Tennant, the team announced.
Tennant was claimed off waivers by the Patriots on Sept. 1, but was waived on Sept. 4 in order to make room for fullback Lex Hilliard.
Originally a fifth-round pick in 2010 by the Saints, Tennant, a Boston College graduate, can play both center and guard.
The Patriots have listed standout guard Logan Mankins as questionable for Week 4 with a hip injury, and Tennant's signing could be to add depth in the event that Mankins is unable to play. Reserve center/guard Nick McDonald (shoulder) is also listed as questionable on the injury report.
