Porter (ankle) is listed as questionable for Sunday's game against the Packers, Patrik Walker of the Cowboys' official site reports.
Porter was dealing with an illness earlier in Week 6 prep, but he's now listed as questionable after logging a limited practice Friday due to an ankle injury. With Cobie Durant (hamstring) ruled out, Ameer Speed (knee) would likely start at outside cornerback opposite DaRon Bland if Porter is not able to play.
