ALAMEDA -- The Raiders are banged up without much time to recover before Thursday night's game against the L.A. Chargers.
Raiders coach Jon Gruden said three players were set for MRIs on Monday, and a source said the results were mixed.
Further testing confirmed Raiders fears that defensive end Arden Key had suffered a broken foot. He's expected to miss significant time, a real setback for a second-year pro who's starting to finish sacks and make positive strides. He had sacks in back-to-back games, including a third-down takedown in Sunday's victory over the Lions.
The news was better for star right tackle Trent Brown. His MRI showed no significant damage, and there's a chance he could play against the Chargers. He could be questionable for that game, though that won't be known until Wednesday's injury report is released.
Cornerback Daryl Worley has a strained Achilles' tendon that is not torn. Worley had an MRI but should be OK moving forward, though the quick turnaround puts his status in some question.
Center Rodney Hudson missed the Lions game with an ankle sprain, and the Raiders aren't sure if he'll be able to play against the Chargers. He practiced Friday and was active some in pre-game warmups but ultimately was rendered inactive.
"I don't know how close he was. He gave it everything he could," Gruden said of Hudson. "I don't know his status for this game, either. I'll cross my fingers. He just couldn't push off [the injured ankle]."
Players were given Monday off, but the team had to submit an estimated participation report anyway. Nicholas Morrow showed up there with a groin injury.
Also, the Raiders formally activated cornerback Isaiah Johnson off injured reserve. Linebacker Brandon Marshall was waived in a corresponding move. The veteran was back with the team for less than a week. Fellow new linebacker Will Compton was activated over him and played defense and special teams.
Here's the estimated participation report submitted by the team:
