If Sunday doesn't go the way they want it to, the 7-8 Dallas Cowboys could be packing their bags for the season.

To visit the postseason, Dallas needs a win over the Washington Redskins and a Philadelphia Eagles loss to the New York Giants. If not, the already-disappointing season will end miserably.

That's not the only thing that could end on Sunday.

37-year-old tight end Jason Witten could be playing for the last time on Sunday if the Cowboys don't win. The Hall of Fame-bound tight end came out of his one-year retirement in the offseason with the thought of resuming his career. Being that he's on a one-year career and he's not exactly young for football, there is a possibility he retires again after the season.

However, Witten insists that the 2019 campaign season will not contain his last NFL snaps.

“I really don't envision this being my last game,” Witten said, via David Moore of the Dallas Morning News. “I just haven't approached it that way. We'll see what happens down the road.”

While Witten doesn't envision Sunday being the end of his NFL career, that does not mean he's guaranteed to come back in 2020. Instead, it may mean that he is talking about the postseason, keeping up an optimistic attitude for a season lacking optimism.

Witten is the Cowboys' all-time leader in receptions (1,211) and receiving yards (12,953). Dallas is the only city he's called an NFL home. They drafted him in the third round of the 2003 NFL Draft out of Tennessee.
