The Cowboys have a scheduled visit with free agent defensive tackle Henry Melton on Monday, according to a source.
Melton visited Seattle late last week and could have more planned if he doesn't reach a deal with the Cowboys.
Melton played in just three games with the Chicago Bears last season before suffering a torn ACL. While it's expected Melton will recover in time for training camp, he must prove to NFL teams, looking to sign him, health won't become a problem during the 2014 season.
The Cowboys are looking for a replacement for defensive tackle Jason Hatcher, who signed a four-year contract with the Washington Redskins, late last week. Melton is a favorite of Cowboys' defensive coordinator Rod Marinelli, who coached him to a Pro Bowl berth while they were in Chicago in 2012.
Melton is the biggest free agent to visit Valley Ranch since the period started last Tuesday. The Cowboys are looking to upgrade the defensive line and have expressed interest in Julius Peppers (signed with Green Bay), Jared Allen, Robert Ayers and Melton.
The Cowboys would also like to bring back one of their own free agent defensive lineman in Anthony Spencer. Spencer, who is coming off a torn ACL, is visiting the New York Giants on Sunday and visited the Washington Redskins along with Hatcher, last week.
