The Cowboys will host Mississippi State defensive tackle Fletcher Cox.
Cox, a 6-foot-4, 298-pounder, can play defensive tackle in a 4-3 scheme or end in a 3-4 formation.
While the Cowboys use a base 3-4 defense, coach Jason Garrett has said they will use four-man fronts at times.
The Cowboys will host 30 draft-eligible players this week and host 20 more players at their annual Dallas Day for area players.
Mel Kiper has Cox ranked the third-best defensive tackle in the draft behind Memphis' Dontari Poe and LSU's Michael Brockers. Poe, whom Cowboys owner/general manager Jerry Jones said he was impressed with, is not scheduled to visit Valley Ranch.
Here's another scouting report on Cox from NFL Draft Scout.
Cox is ranked 19th among the best players in the draft, according to Scouts Inc.
