ALAMEDA, Calif. (AP) - Oakland Raiders strong safety Tyvon Branch practiced Friday for the first time this week but remains questionable with a neck injury.

Injuries are also taking their toll on the Raiders offense. Running backs Darren McFadden and Mike Goodson are both out with foot injuries, while wide receiver Darrius Heyward-Bey is questionable with a hamstring injury.

Branch, who signed a four-year, $26.6 million deal in the offseason after being hit with the franchise tag, has started 57 consecutive games for Oakland.

The Raiders are already thin in the middle of their secondary.

Free safety Matt Giordano missed practice earlier this week after suffering a concussion against Baltimore. Michael Huff, the starting free safety at the beginning of the year, has been playing cornerback since Week 3.
