CEDAR FALLS, Iowa (AP) – Northern Iowa senior guard Anthony James, the leading returning scorer for the Panthers, has been suspended for the first three games of the upcoming season.    Northern Iowa coach Ben Jacobson announced Tuesday that James is suspended for violating team and athletic department policies.  Jacobson says he’s disappointed for James, but adds that the situation has been put behind the team. James averaged 12.5 points per game for Northern Iowa in 2011-12. He’ll miss games against Wartburg, Toledo and North Dakota.
