Lions cutdown: Jahvid Best to PUP

We noted the first phase of the Detroit Lions' roster cutdown earlier Monday. The second phase, spelled out in full on the team's website, mostly consisted of placing injured players on various reserve lists.

At the top of list is running back Jahvid Best, who ended up on the physically unable to perform (PUP) list, as ESPN's Adam Schefter reported he would two weeks ago. Best, who hasn't been cleared for contact 10 months after suffering a concussion, is ineligible to play for the first six weeks of the season. At that point, a three-week window will open during which he can begin practicing. After that, another three-week window opens for the Lions to either add him to their roster or end his season.

The Lions also placed cornerback Chris Greenwood, their fifth-round draft pick, on the PUP list because of an abdominal injury. Offensive lineman Bill Nagy, a promising prospect claimed earlier this month from the Dallas Cowboys, was placed on injured reserve and will miss the season.

Meanwhile, the Lions have yet to confirm reports from Washington, D.C., where Redskins cornerback Kevin Barnes told multiple media outlets he had been traded to the Lions.
