Injuries have been a running theme at Cardinals training camp so far.

Linebacker Sean Weatherspoon (hamstring) was expected to return to practice, but experienced a setback on Tuesday.

In the best interest of the team and for himself, Weatherspoon will remain sidelined.

"I want to practice and be out there with my guys, get that timing down with them," Weatherspoon said. "The main thing is, I'm on a one-year deal so I have to be healthy before I get out there. That's what it's all about."

The Cardinals signed Weatherspoon in hopes that he could recapture his pre-injury form.

The former first-round pick missed the entire 2014 season with a ruptured Achilles tendon he suffered while with the Atlanta Falcons.
