Brandon George of the Dallas Morning News passed along confirmation of the Raiders' decision from the defensive end's agency, Reign Sports. Todd Archer of ESPN.com previously reported the Cowboys' offer sheet was a three-year, $8.25 million deal with a $3.3 million signing bonus.
David Moore of the Dallas Morning News noted the decision cannot become official until Wednesday:

While Raiders have informed Cowboys they won't match offer to DE Benson Mayowa, club retains right to change mind. Not official until Wed.3/22/2016, 1:56:23 PM
Mayowa is a raw talent that went undrafted out of Idaho in 2013. After a short stint with the Seattle Seahawks, he's spent the past two seasons as a limited contributor for the Raiders.
The 24-year-old defensive lineman has registered just 32 combined tackles with two sacks and one forced fumble in 30 career games. So it's clear the Cowboys are paying him based on what they believe he can become and not what he's already accomplished.
Clarence E. Hill Jr. of the Star-Telegram provided comments from team vice president Stephen Jones after signing the defender to the offer sheet:
We are looking for players who have value and are efficient for us. I don't know how the Raiders view it. But we are looking at guys we can get value out of. That is what we did with Benson. We like him as a player and we think he can fit in our defensive scheme.
He added: "Is he the next DeMarcus Ware? Probably not. Is he the next Charles Haley? Probably not."
In other words, it's important to keep expectations within reason despite the usual spike in hype when a player signs with America's Team. He's a player the Cowboys hope can find a comfort zone within their system and perhaps grow into an impact performer.
It's a worthwhile chance to take for Dallas. Even though the Raiders reportedly opted against matching the offer sheet, it's not an overly lucrative contract. The Cowboys needed additions to the front seven after finishing with just 31 sacks last season, which ranked 25th in the league.
Mayowa is not the type of player who's going to solve those issues by himself. But he can provide depth while the Dallas coaching staff works to bring out his untapped potential.
