Bush, who entered the upcoming NFL draft as a junior, had a new rod inserted and was expected to be released from a Louisville hospital on Wednesday, spokesman Rocco Gasparro said. Gasparro said Bush sought another medical opinion when his bone didn't heal quickly enough. He's expected to be out another couple of months and won't be able to work out Monday during Louisville's pro day, Gasparro said. Bush decided to skip his senior season, despite playing in only one game as a junior. In his sophomore year, Bush ran for 1,183 yards and an NCAA-leading 23 touchdowns. He scored three touchdowns in the first half of the season-opener against Kentucky last year before breaking his leg early in the second half. The Cardinals went on to finish 12-1, beating Wake Forest in the Orange Bowl.
