Gabbert handled most of the reps with the first-team offense at Wednesday's practice, Darren Urban of the Cardinals' official site reports.
Gabbert's standing has been elevated due to injuries to Arizona's top two signal callers. With Carson Palmer (arm) on injured reserve, Drew Stanton has started back-to-back games, but in the Week 10 loss to the Seahawks, he sustained a sprained knee. Stanton is progressing in his recovery and practiced on a limited basis Wednesday, but the Cardinals seem to be preparing for the prospect of Gabbert under center this Sunday at Houston. Expect head coach Bruce Arians to make a decision on his starting quarterback by the end of the week.
