The school's athletic department released the information in a statement Monday night.
This is the statement, presented verbatim:
"Penn State freshman defensive end Shawn Oakman has been dismissed from the football team due to a violation of team rules."
Oakman is a 6-foot-7, 260-pounder.
Team sources say he had an adjustment period while playing on the foreign team last season but improved significantly as the year progressed and was likely to be an impact player in 2012.
