Zach Osborne, riding for the Rockstar Energy Husqvarna Factory Racing team, injured his shoulder ahead of Redbud. He is currently sitting at sixth overall in the 450 class in the Lucas Oil AMA Motocross Standings and 14th overall in the 450 class in the Monster Energy Supercross Championship. The hopes are that Zach may be back for the next AMA Motocross event at Spring Creek in Millville, Minnesota.
