As if a new coach, a new quarterback, wholesale changes on both sides of the ball and four years of non-winning records weren't concern enough at ASU, the Sun Devils got more bad news when coach Todd Graham announced that running back Cameron Marshall will not be tackled the rest of training camp.

"We're just resting him,'' Graham said. "He won't scrimmage Saturday or any of that, not that he couldn't. He's done being tackled."

Asked if Marshall's ankle is an issue, Graham said, "No, he's just fatigued."

Graham battled ankle issues all of last season and had minor surgery in the spring. He’s been limited in practice the past two days.

At Pac-12 media day last month near Los Angeles, Marshall said he felt great. Last season, he rushed for 1,050 yards and tied a school record with 18 rushing touchdowns. This season, he's expected to be the featured back in Graham's “high-octane” attack.
