Notre Dame looked beaten and Michigan State looked unstoppable. Then, in a stunning turn of events, cornerback Terrail Lambert capped a furious rally by returning an interception 19 yards for a touchdown with 2:53 remaining to give the 12th-ranked Fighting Irish a 40-37 victory over the Spartans on Saturday night. The loss stunned Michigan State (3-1) and its pumped-up fans, who remained in the stands despite heavy rain in the second half, convinced they were going to see the Spartans beat the Irish (3-1) for the eighth time in 10 games.
