Wentz "is likely to start" Sunday against the Bears if Kyler Murray does not clear concussion protocol, Dan Graziano of ESPN.com reports.
Wentz was named the backup quarterback last week and led the Vikings to a Week 1 comeback victory over the Packers, so although fellow reserve J.J. McCarthy would also be an option, Wentz appears to be the favorite to get the nod should Murray be unable to go.
