The Dallas Cowboys were gasping for air after a collapse versus the Arizona Cardinals and narrow win over the Indianapolis Colts, but their breathing is sounding much better after the New York Giants' Thursday Night football flop. If they can upset the NFC-leading San Francisco 49ers in AT&T Stadium this Sunday, then the divisional deficit will be just one game. Though, “America's Team” is unlikely to reach that standard unless its defense rapidly improves. An injury-hampered Joey Porter Jr. seemingly caps the unit's ceiling.

The 26-year-old cornerback continues to battle a foot issue, leaving his status versus the Niners in considerable doubt. Jerry Jones is not denying the obvious: this is a rough situation. But he still believes in Porter's ability and is optimistic that better luck is coming.

“It's frustrating,” the Cowboys owner said, per Jon Machota of The Athletic. “But I'm not so sure that's the word. It's just the life we've chosen. There's no question having him on the field is a significant advantage, so hopefully he'll be out there (Sunday).”

Dallas knew the risks of acquiring the former second-round draft pick, or last it should have. Porter engaged in a tense contract battle with the Pittsburgh Steelers and did not suit up until after he was traded at the end of September. The body can struggle to withstand punishment after a long layoff. Unfortunately, the Cowboys do not have the luxury of gradual transitions.

Their defense showed life against the Colts but has stumbled for most of the campaign. Joey Porter Jr. instantly became an integral member of the squad. He has carried himself well when on the field, allowing a meager 39.6 passer rating and 6.3 yards per reception in four games, according to Pro Football Focus. He also has three passes defended and eight combined tackles.

Will those numbers change in Week 10? Jerry Jones and Cowboys fans want Porter to lead the secondary past Brock Purdy and the 49ers. How Porter's health progresses moving forward could have a huge impact on an intriguing NFC East race.
