Mathieu (heel) has no injury designation ahead of Sunday's matchup with the Cowboys, Mike Triplett of NewOrleans.Football reports.
The 12-year veteran went from logging a DNP on Wednesday to a full practice session Friday, indicating that he's moved past his heel injury. Mathieu recorded four total tackles and one forced fumble during the Saints' Week 1 win, and he'll look to build on that impressive showing Sunday.
