CEDAR FALLS, Iowa -- Anthony James scored 16 of his 18 points in the second half and Northern Iowa blew past a frustrated Iowa 80-60 for its seventh straight win.
Jake Koch added 13 for the Panthers (8-1), who are 3-0 against major-conference opponents this season.
Northern Iowa led by just two points midway through the second half. But three consecutive technical fouls by the Hawkeyes helped spur a decisive 20-2 run by the Panthers.
Iowa coach Fran McCaffery was ejected with 4:47 to go after drawing his second technical.
Devyn Marble had 14 points to lead Iowa (5-4), which played without starting point guard Bryce Cartwright. Iowa spokesman Matt Weitzel says Cartwright was nursing a sore hamstring.
