Thousands of angry soccer fans staged a six-mile march in Lusaka, Zambia, to protest what called biased refereeing in the match that kept Zambia out of the World Cup finals. Zambia’s team was beaten 1-0 by Morocco in the final of their Group B World Cup qualifying round Sunday in Casablanca.

Zambian soccer officials filed a complaint Monday with FIFA, soccer’s international governing body, against Jean-Fidel Diramba, the Gabonese referee. The Zambians complained Diramba favored Morocco.

The NBA argued in federal court in Newark that Chris Dudley’s seven-year contract with the Portland Trail Blazers is an attempt to “subvert” the league’s salary cap. Howard Ganz, an NBA lawyer, said the salary cap is designed to put all teams on “equal footing on bidding for players,” but the one-year escape clause in Dudley’s contract undermines such plans.
