Arizona State quarterback Sam Leavitt will miss Saturday’s road game against Cincinnati due to injured ribs, coach Kenny Dillingham said Wednesday.Jeff Sims will start for Arizona State against the Bearcats.Leavitt injured his ribs in the second quarter of last Friday’s 27-19 victory over Utah but returned a short time later and finished out the game.Dillingham said Leavitt could miss multiple games. The Sun Devils (5-1, 2-1 Big 12) have a bye next week.”I could give you a timeline but it’s not real,” the Arizona State coach said. “It could be two weeks, it could be four weeks. Hopefully the sooner the better. … We’re going to get through this week and then the bye week, half the bye week, and reassess it as it goes.”Sims is a former starter at Georgia Tech (23 starts) and Nebraska (two) who transferred to Arizona State following last season. Leavitt beat Sims out for the Sun Devils’ starting gig in fall camp.
