Cowboys' Jason Witten uncertain how much longer he'll play in the NFL
UNDISPUTED ON FS1

The Dallas Cowboys are set up to be a very good football team for a very long time. Dak Prescott and Ezekiel Elliott breaking out in their rookie seasons was a promising sign of a potentially bright future, but although those two aren't going anywhere, the future of Tony Romo and Jason Witten remains uncertain.

Romo's future in Dallas is bleak, to say the least. The veteran quarterback will likely be playing in a different uniform next season. Witten, however, will remain in Dallas in 2017, but his future beyond next season is up in the air. The longtime Cowboys tight end said the following about his future after the 2017 campaign, via Zac Jackson of Pro Football Talk:

“I think at this point you just go into it and look at it one year at a time,” Witten said, per the Dallas Morning News. “I wouldn’t rule out [playing past 2017], but I don’t think I’m going to be making an announcement that this is it either. I know how much it takes to put into it, so you don’t know what you’re going to feel like.”

With the exception of his rookie year in 2003, Witten has played in all 16 regular season games in every year he's suited up for the Cowboys. The 34-year-old is a prime example of consistency and durability in the NFL as he is as dependable as any player in the league at his position.

The resurgence of the Cowboys offense with Prescott, Elliott, and arguably the best offensive line in the NFL bodes well for Witten's future even if he's on the wrong side of 30. Romo, Witten's longtime teammate, may be headed elsewhere but Witten can probably continue to play at a high level into his late 30s. 

Witten will become an unrestricted free agent in 2018. The veteran tight end will make $7.4 million in the final year of his contract with Dallas.
