Barkley signed with the team earlier this week.
Gabbert’s last start came, coincidentally, against the Cardinals on Oct. 6, 2016, in Week 5 last season.
Arians thinks, as long as the Cardinals can keep the Gabbert “in his comfort zone” he should be OK against the Texans.
“He can spin it as good as anybody I’ve ever had,” Arians said earlier this week. “Don’t overload him with things he has to think about for this week because they’re such a good pressure team. Let him know his protections are sound. Keep him in his comfort zone because he can spin the ball. As long as we’re getting open, we’ve got to catch it.”
Gabbert will be playing for his seventh coach and seventh offensive coordinator in his seventh scheme since getting drafted 10th overall in 2011 out of Missouri.
