Cowboys make several roster moves

IRVING, Texas -- The Dallas Cowboys made some roster moves during the first day of the rookie minicamp Friday.

The biggest was signing defensive tackle Amobi Okoye to a two-year contract.

"We like a lot of things about him," coach Jason Garrett said. "He was a high draft pick a few years ago, a really young player coming out of school and he has a lot of talent. Rod [Marinelli] was around him in Chicago, we know him well, he's had an intimate-type relationship. So we think that's a real positive thing. He's had some health issues the last year or so where he lost a lot of weight. He's gained his weight back and we're waiting on some medical things. We feel like he has a chance to be a contributor on that defensive line."

Garrett said Okoye passed his physical Thursday but there are medical issues that need to be cleared up relating to an undisclosed health problem.

Okoye was the 10th overall pick by the Houston Texans in the 2007 draft and started 58 of 62 games in four seasons. He played 25 games for Marinelli in 2011 and 2012 with the Chicago Bears before a health issues cost him his 2013 season.

The Cowboys also signed offensive lineman Jerrod Black from Iowa State as a workout player. Black was one of the 30 national visits the Cowboys hosted during the draft process.

Also, the team released linebacker Jonathan Stewart.
