TEMPE, Ariz. (AP) - Arizona State rushing leader Ryan Torain will miss the rest of the season because of a toe injury.

Sun Devils coach Dennis Erickson said Wednesday that the senior back has either a dislocated or broken big toe, possibly both. Torain was hurt in the first quarter of the No. 12 Sun Devils' victory over Washington on Saturday.

Torain had started six of the seven games for the unbeaten Sun Devils, rushing for 553 yards and five touchdowns. He also caught seven passes for 100 yards and two scores.

The injury leaves the starting running back spot to junior Keegan Herring, who has run for 480 yards.

Arizona State (7-0) is off this week. The Sun Devils' next game is Oct. 27 at home against No. 10 California.
