IRVING, Texas -- Are the Dallas Cowboys about to see the allure of Rod Marinelli?

According to multiple sources, the Cowboys have a visit scheduled with defensive tackle Henry Melton and have interest in defensive end Julius Peppers. Melton is set to visit the Seattle Seahawks, according to reports, and has also visited the Minnesota Vikings.

Marinelli, the Cowboys' defensive coordinator, coached both players to Pro Bowl performances with the Chicago Bears. The duo would help a defensive line that lost DeMarcus Ware (Denver Broncos) and Jason Hatcher (Washington Redskins) the past two days and could lose Anthony Spencer.

Melton is coming off a torn anterior cruciate ligament. But at the NFL scouting combine last month, Jordan Woy -- Melton's agent, who also represents Hatcher -- said Melton had just started running and should be good for training camp.

Melton played in only three games in 2013, but he earned Pro Bowl honors in 2012 with six sacks and two forced fumbles after a seven-sack season in 2011.

Peppers was cut this week by the Bears because of his $13.9 million base salary and $18.183 million salary-cap figure. He had seven sacks in 2013, but in three years with Marinelli he had 30.5 sacks. He is 34 years old and has not missed a game since 2007.

As with everything, it all comes down to price for the Cowboys. They have the cap room (roughly $7 million) to sign both players, but they will not shell out huge money to a player coming off an injury or an older player, without some sort of protection.
