ALAMEDA — Second-year cornerback DJ Hayden is slated to practice this week for the first time in almost five months, Raiders coach Tony Sparano said Monday.

Hayden suffered a right foot injury during an offseason workout with the team in late May that required surgery a short time later.

He missed all of training camp, all four exhibition games and Oakland’s first five regular-season games while on the physically unable to perform list.

Players on the PUP list are required to miss at least the first six weeks of the season. Once a player is removed from the PUP — at any point during a five-week period that starts this week — the team has a 21-day window in which to evaluate the player before making a decision on whether to activate him to the 53-man roster, waive him or place him on season-ending injured reserve.

In recent days, Hayden was spotted on the practice field working with an athletic trainer, while his teammates practiced on an adjacent field.

Hayden missed the final eight games last season with a groin injury. He also missed significant time during offseason workouts and training camp last season while he recovered from a surgery to remove scar tissue related to a near-fatal chest injury in college.

The Raiders are hopeful that Hayden can develop into the kind of top-tier player they envisioned when they selected him with the 12th pick of the 2013 NFL draft.

Hayden had his ups and downs during his rookie year, but he showed signs of being able to bolster a Raiders cornerbacks corps that has featured two new starters each of the past four seasons.

It’s likely that the Raiders will activate Hayden at the end of his evaluation window and use him as an extra defensive back until he rounds into shape. Tarell Brown and Carlos Rogers remain the starters.

Hayden wasn’t available for comment Monday. He is expected to speak with the media Wednesday.
