The Vikings might have known that the Giants would lose Domenik Hixon for the season. Court documents filed by the team in a lawsuit involving the Metrodome cite "an NFL study that found the rate of anterior cruciate ligament injuries is 88 percent higher in games played on FieldTurf than in games played on grass." Hixon tore his ACL without contact in the first football practice on the FieldTurf at New Meadowlands Stadium. He is out for the season. According to the Minneapolis St. Paul Business Journal, the company that runs the Metrodome "rejected FieldTurf's bid after the Vikings expressed concerns about the safety of the company's product — the main reason for replacing the Dome's existing turf in the first place." FieldTurf USA is suing to stop the Vikings from using a competitor's turf product.
