Minshew is slated undergo testing on his right elbow/arm in the wake of Sunday's loss to the Seahawks, according to Darren Urban of the Cardinals' official site.
Minshew took over as the team's starting QB in advance of Week 9 action, and now his status for this weekend's game against the Rams is unclear. In the event that Minshew's issue ends up being long-term, which could be a possibility per Josh Weinfuss of ESPN.com, Carson Beck would be next in line for Arizona's signal-caller reps.
