Remember when 49ers fans overtook Dallas in the 2014 season opener? It looks like Cowboys fans returned the favor Sunday.

Said Cowboys quarterback Dak Prescott: “It’s America’s team and we kind of expect that everywhere we go the fans to show up like that, so we’re thankful for them.”

#49ers Joe Staley on all those #Cowboys fans: “We’re sitting 1-3 right now, so we have to do our job to make sure our fans come out for us.” — Eric Branch (@Eric_Branch) October 3, 2016

There’s no doubt Dallas’ fans were loud and proud Sunday as the road team took the 24-17 victory, coming from behind after the 49ers’ got out to a 14-0 lead in the first half.

If the 49ers season goes off the rails – a possibility considering NaVorro Bowman may have suffered a torn Achilles – opposing fans taking away San Francisco’s home field advantage might become a regular thing during the remaining six home games.
