That list includes former Cowboys quarterback Tony Romo and former Cowboys wide receiver Dez Bryant, amongst others. Witten, Jerry Jones and the organization will hold a press conference at 2 p.m. Thursday to announce the retirement.
The news might actually hit hardest for fans of the Dallas Cowboys. For the past 15 seasons, Witten became one of the all-time faces of the organization due to his accomplishments.
On the field, the Tennessee product was a pillar of consistency. In his career, he hauled caught the fourth most receptions in league history (1,152), trailing just Jerry Rice (49ers and Raiders), Tony Gonzalez (Chiefs and Falcons) and Larry Fitzgerald (Cardinals.
Witten is the Cowboys' all-time leader in receiving yards (12,448) and ranks third in franchise history with 68 receiving touchdowns.
As a team captain, he was a strong influence in the lockeroom and took on a major leadership role for much of his career.
Witten was also a positive influence in the community. Throughout his time in the pros, he never hesitated to donate to charitable causes or spend hours with those less fortunate than himself.
For all of the reasons above, it's easy to see why Cowboys Nation showed Witten a ton of love on social media.
