As expected, the news on Wisconsin cornerback Devin Smith isn't good.
Smith underwent left foot surgery Monday and will miss the remainder of the season, Badgers coach Bret Bielema said Tuesday. He has a redshirt available, so he'll return in 2012 as a fifth-year senior.
Smith suffered the injury in the first quarter of last week's win against Oregon State.
Junior Marcus Cromartie moves into Smith's starting spot, beginning Saturday against a strong Northern Illinois offense. Although Wisconsin is loaded at several positions, cornerback isn't one of them, and the Badgers need Antonio Fenelus and Cromartie to stay on the field.
