On Sunday, McFadden was released by the Cowboys after being a healthy scratch for all but one game this season.
The Giants-Cowboys games have been such ratings catnip for the networks that they are nearly always played in prime time.
McFadden's best career in the National Football League came in 2015 with Dallas, when he rushed for 1,089 yards (fourth in the NFL) and 4.6 yards-per-carry (third in the NFL).
"Finally, I just want to say that I make this decision not with sadness or without further opportunity, but with a couple of days to reflect on how I feel and where I am at this stage of life", McFadden said.
The former Razorback said he'll now be spending more time with family and pursuing other interests and "of course, going to a few Arkansas football games".
McFadden ran for 5,421 yards and 28 touchdowns in his career, the first seven seasons with the Oakland Raiders.
He had two seasons in which he eclipsed the 1,000-yard mark and also scored five times on receptions.
Arkansas fans remember McFadden as one of the best offensive performers in school history.
In a statement posted to his Twitter account, McFadden thanked his family, coaches and teammates throughout his journey.
