According to David Moore of the Dallas Morning News, ESPN offered Witten $4-4.5 million per year as a broadcaster.
Meanwhile, Chris Mortensen of ESPN reported a different network provided another "interesting" offer that could make his decision more difficult. He will reportedly make a final decision between the networks or a return to the Cowboys by Wednesday.
Witten had just signed a new four-year deal worth $29.6 million last season, but he recently restructured his contract to provide $3.5 million in more cap space for the Cowboys.
Considering he is set to turn 36 years old next Sunday, there was no guarantee he would play out the contract. The veteran finished last season with 63 catches for 560 yards, which were both his lowest marks since his rookie season in 2003.
Still, the Cowboys were expecting at least a few more productive years out of Witten.
Clarence Hill Jr. of the Star-Telegram reported the player "blindsided them late in the process." However, Jerry Jones made it clear nothing was final.
"He has not made any decisions that are definite at this time," Jones said Friday, per Rob Phillips of the team's official site. "We have no announcement today as it pertains to Jason’s future other than to say that he’s a wonderful and valued member of our organization and our family."
Dallas did select a tight end, Stanford's Dalton Schultz, in the fourth round of the draft.
Meanwhile, Witten could follow in the path of former teammate Tony Romo, who retired before seamlessly joining the top broadcasting team on CBS.
