Nagy, a seventh-round pick out of Wisconsin in 2011, is a versatile interior lineman who has experience playing both guard and center.
"He's a very interesting player," Schwartz said. He played on the offensive line when we played down in Dallas (last year) -- thought that he did some really good things. He was a guy that had an injury early on and he had an injury-marred career at Wisconsin, but it didn't take away the fact that he was a good player. He's in injury rehab right now but I think that he has a future for sure with us."
Nagy was involved in a Moped accident in 2009, suffering multiple injuries including a broken wrist and heel. He returned to start eight games as a senior in 2010, filling in at various spots on the Badgers offensive line.
As a rookie for the Cowboys last season, he started the first four games of the regular season before fracturing his ankle and landing on injured reserve.
