Grier (coach's decision) is inactive for Sunday's game against the Giants, Michael Gehlken of The Dallas Morning News reports.
Grier hasn't dressed for Dallas since Week 8, when top backup Cooper Rush made a spot start against the Vikings while Dak Prescott was sidelined with a calf injury. Expect Grier to remain a fixture on the inactive list the rest of the season so long as Prescott and Rush are both available on gamedays.
