Dallas Cowboys quarterback Tony Romo has been listed as questionable for his side's clash against the Arizona Cardinals with a back problem.
The 34-year-old aggravated his injury during his side's defeat to the Washington Redskins on Monday when he took a powerful hit from Keenan Robinson.
Romo returned to the game after treatment, but struggled with his footwork and throwing motion in the overtime loss at AT&T Stadium.
He has missed all of his side's practice sessions this week, but will participate in their walkthrough session ahead of the game to determine whether he will face the Cardinals, according to NFL Network.
Brandon Weeden is on standby to play for the 6-2 Cowboys if Romo is unable to take the field.
