Henry Melton returned home without a contract with the Seahawks, giving the Cowboys an opening to sign him. The Grapevine product has a visit scheduled at Valley Ranch on Monday, according to a source.
Melton visited the Vikings late last week, and the Raiders, Rams and Bears also have interest.
Melton wants a short-term deal to prove his health after undergoing reconstructive surgery on his left knee in October.
The Cowboys seek a replacement for defensive tackle Jason Hatcher, who signed with the Redskins last week. Melton played the three-technique for current Cowboys defensive coordinator Rod Marinelli when Marinelli was defensive coordinator of the Bears. He earned Pro Bowl honors in 2012 playing for Marinelli.
Melton, 27, played only three games last season because of a torn anterior cruciate ligament. But in four seasons, he has 15.5 sacks.
The Cowboys have lost Hatcher and defensive end DeMarcus Ware, who signed with the Broncos after being released by Dallas, off their defensive line. They also could lose defensive end Anthony Spencer, who visited the Giants on Sunday.
Spencer already has visited the Redskins.
The Cowboys have interest in retaining Spencer, who had microfracture knee surgery after playing only 34 snaps last season. Free agent defensive end Jared Allen appeals to them, too, if his price tag falls.
The Cowboys lost a chance at defensive end Julius Peppers after he agreed on terms with the Packers on Saturday.
With only around $7 million in salary-cap space, the Cowboys continue to seek deals that make monetary sense.
