Coach Bruce Arians said Ward has a dislocated wrist and will need surgery. He will be out for 12 weeks, the team announced.
In other injury news, Arians said that it is "very iffy" whether wide receiver John Brown will play in Arizona's second preseason game against Oakland. Brown has been sidelined with a quad injury since last week.
Arians added that outside linebacker Jarvis Jones has an injured disc in his back and should miss a week at the most.
Here are the other injuries we are monitoring on Saturday:
Niners guard Josh Garnett is dealing with a knee injury, per The Sacramento Bee. The Bee reported Garnett is expected to miss practice time, but the injury is not thought to be season-ending. Shanahan said surgery is an option for Garnett.
- Washington Redskins outside linebacker Preston Smith will miss some time after suffering a sprained ankle on Thursday, The Washington Post reports. Washington coach Jay Gruden told reporters Smith's foot is in a boot and the linebacker is expected to miss "a week or two." Smith's absence frees up more first-team snaps for rookie Ryan Anderson and veteran Junior Galette.
