Lions re-sign Nate Ness, release Cory Greenwood

On Friday morning, the Detroit Lions made another change to their roster before finishing up their preparations for Saturday's preseason opener. Specifically, they added another defensive back by re-signing Nate Ness, and they made room for him by releasing linebacker Cory Greenwood.

Greenwood had actually been excused from practice the last couple days, so it's interesting timing that he was released on Friday. Originally claimed off waivers by the Lions last year, Greenwood ended up spending the entire 2013 regular season on injured reserve. This year, he was hoping to make the team primarily as a special teams contributor, but that obviously won't be happening now.

With an open roster spot, the Lions brought back Ness, who actually spent a few weeks with the team earlier this offseason. He was signed in April and released after the draft in May. Here's more on Ness from our first post on him:

As for Ness, he's been in the NFL since 2009. He began his career as an undrafted free agent out of Arizona, and he's spent time with several teams, including the Miami Dolphins, Seattle Seahawks, St. Louis Rams and, most recently, Carolina Panthers.

With the Lions simply swapping out players on defense, they remain at 90 players overall going into Saturday's preseason opener.
