In a move that was expected, the team officially announced it placed the cornerback on reserve/physically unable to perform list Tuesday. Hayden will sit out the first six games of the 2014 season.
Hayden underwent foot surgery for a stress fracture in late July.
Raiders coaches had been leaning toward placing Hayden on reserve/PUP for the past couple of weeks. The team hopes to give the second-year player plenty of time to get healthy, in shape, and the Raiders won't have the temptation of putting him on the field before he's ready, per NFL Media Insider Ian Rapoport. When Hayden returns, they want him to be primed to play.
The No. 12 overall pick in 2013 has been a disaster thus far, mainly due to his inability to stay healthy. Hayden played in just eight games as a rookie, starting two, and didn't perform spectacularly when on the field. He'll add at least another six missed games to his two-year tally.
Some other injury news we are tracking:
2. Anthony Spencer (knee) won't be ready Week 1, but Jerry Jones said Tuesday the Cowboys' defensive end would avoid the PUP list, per the team's official website. The sooner he can get back, the better for a Dallas defense that is likely to struggle.
3. More good Cowboys news: Tony Romo returned to practice after sitting out Monday. The quarterback got battered in last weekend's preseason game against Miami. Romo went through individual drills during the portion of practice open to the media.
5. Vikings defensive tackle Linval Joseph practiced for the first time since suffering a minor injury earlier this month when -- as an innocent bystander -- he was shot in the calf by a stray bullet. Joseph said he plans to play Week 1.
9. Raiders linebacker Sio Moore returned to practice on Tuesday, per CSN Bay Area. Moore suffered a scary neck strain in last week's preseason game and was carted off the field. His quick return is a great sign. Right tackle Menelik Watson (hip) also returned to practice after suffering an injury in the game.
