09:46 AM ET 12.07 | Arizona State head coach Todd Graham promised "an electric atmosphere" for Saturday's Pac-12 championship game against Stanford. His team, though, won't have its sparkplug, tailback Marion Grice. Grice, the team's leading rusher and third-leading receiver, will miss the game because of a lower-leg injury, Graham said Friday. Sophomore D.J. Foster, who also has played slot receiver, will start in place of Grice, whose touchdown total (20) ranks fifth in the nation. De'Marieya Nelson, a 6-foot-3, 226-pound H-back, also will play tailback. "It's a big loss," Graham said, "but they showed last week the kind of depth that we have at that position."
