Ferguson (ankle) did not practice Thursday, Todd Archer of ESPN.com reports.
Ferguson's back-to-back absences to kick off Week 9 prep don't bode well for his availability Sunday against the Colts. He sustained a low-ankle sprain after playing just four snaps during Dallas' Week 8 loss to the Cardinals. Brevyn Spann-Ford worked as the team's top TE after Ferguson's exit. Ferguson will have one more opportunity to practice Friday before Dallas posts Week 9 game statuses.
