No foul. The Maine player was shoved from behind a team mate!
How does the ref on the sideline not over rule his partner there? I can see the ref on the baseline getting fooled because he's behind Purvis and just sees the Maine player go down. But the other ref has a clear side view that Purvis was 2 feet from the Maine player. It's pretty comical seeing how bad a call that was.
it's early, the Refs are rusty too
