Marcel Reece back on field after foot scare

ALAMEDA, Calif. -- The Oakland Raiders received some good injury news Tuesday: Fullback Marcel Reece returned to work in the early portion of practice.

Reece suffered a foot injury Friday against Detroit. He left Sunday’s practice early and did not practice Monday. Oakland coach Dennis Allen said Monday that Reece would get an MRI. Clearly, the results did not show any major issues.

Tuesday, Allen said Reece was limited and will be eased into action.

Reece is a sparkplug to the offense and his presence is vital to the Oakland attack. It is unclear whether Reece will play Friday night in Green Bay in the third preseason game.

In other injury news, receiver Brice Butler was back on the practice field after sitting out Monday with a concussion. Rookie quarterback Derek Carr continued to work Tuesday in practice. He was cleared for limited work Monday after suffering a concussion and a ribs injury against the Lions. It is not known if he will play at Green Bay.

Cornerback DJ Hayden, the No. 12 overall pick in 2013, was not on the practice field when the media was present Tuesday. He did extensive side work Monday. He has been out with a foot injury and there is a chance he could begin the regular season on the physically unable to perform list.
