Penn State freshman quarterback Rob Bolden is doubtful to play Saturday against Michigan, Nittany Lions coach Joe Paterno said Tuesday.
Bolden suffered a head injury in Saturday's game against Minnesota and was experiencing some memory loss Sunday. Paterno said Bolden will undergo more testing on Wednesday.
Should Bolden be ruled out, Matt McGloin will likely make his first career start. McGloin threw two touchdowns in Saturday's win over the Gophers.
