There have been some questions regarding Dallas Cowboys running back Miles Sanders' availability for Week 1 after he missed the team's final preseason game against the Atlanta Falcons due to a shoulder injury.The Cowboys, having just completed the Micah Parsons saga, will go to Philadelphia for the regular-season opener against the Eagles on Thursday night. The Cowboys will be looking for a statement win tonight against the Super Bowl defending champions, and to do that, they will need all hands on deck.Fortunately for Dallas, Sanders did not appear in the team's injury reports this week, suggesting that the shoulder injury that kept him out of the last exhibition game is no longer a problem.The Cowboys brought Sanders in this offseason as a potential contributor to a rushing offense that ranked worst in the league last season. With Rico Dowdle carrying the majority of the workload, the team only managed three rushes over 20 yards and six rushing touchdowns in 17 games.Is Miles Sanders the RB1 on the Cowboys roster?The Dallas Cowboys revamped their rushing department in the offseason, acquiring Jaydon Blue and Phil Mafah via the draft and adding Javonte Williams and Miles Sanders through free agency.It's still uncertain how the Cowboys' running game will pan out this year, but it is expected that Williams will be the team's starter initially.Williams will have another chance to prove himself as the leading rusher in Brian Schottenheimer's rushing offense to start the 2025 season. Williams will need to show the talent level he displayed in college at North Carolina, as he hasn't reached those levels since joining the league in 2021.Although Sanders will only be an option behind Williams on the depth chart, he is also expected to play a significant role in the Cowboys' offense this season.How to watch Cowboys vs. Eagles Week 1 opener?The 2025 regular season will begin at Lincoln Financial Field with the Philadelphia Eagles, the defending Super Bowl champions, hosting the Dallas Cowboys on Thursday Night Football.Game infoDate and Time: Thursday, Sept. 4 at 8:20 p.m. ETLocation: Lincoln Financial Field, Philadelphia, PennsylvaniaTV: NBCAnnouncers: Mike Tirico (play-by-play), Cris Collinsworth (color analyst), Melissa Stark (sideline reporter)Live Streaming: Peacock, DirecTV, NFL+
