Can there be a pass interference behind the line of scrimmage in college football In the NFL there is no pass interference possible on passes that do not go past the line of scrimmage?

Answer 1

In the NFL, there is no such thing as pass interference (PI) on forward passes that do not go past the line scrimmage but I recently watched a College Football game in which a PI was called on a forward that never reached the line of scrimmage even though I always believed that there is no such thing as PI if such pass was in the backfield (behind the line of scrimmage). So I am not clear on the rule concerning passes that do not cross the line of scrimmage, in college football.
