WACO, Texas — No. 2 Baylor’s 45-27 victory over Iowa State may have come at a high price Saturday.

Bears quarterback Seth Russell, who began the game as the national leader in passing efficiency (210 rating) and touchdown passes (27) among FBS quarterbacks, left the game in the fourth quarter with a strained neck after being tackled on a 4-yard run.

Postgame x-rays and a CT scan revealed a fracture in one of the bones of his neck. He will see a specialist next week.

Shock Linwood ran for 171 yards and a touchdown and caught a pass for another score as the Bears (7-0) won their FBS-best 20th straight home game.
