Kenyon Martin and Metta World Peace got into a "heated" verbal argument during a Knicks workout prior to Sunday's game against the Pelicans, according to sources with knowledge of the situation. The two veteran forwards did not come to blows, but the back and forth was described as "intense" by one source with knowledge of the dust-up. World Peace and Martin smoothed things over prior to the Knicks' 103-99 loss to the Pelicans on Sunday night, sources with knowledge of the situation said. These dust-ups, of course, are typical of the frustration that surfaces when teams are losing. The Knicks have lost nine straight games and are tied with Milwaukee for the worst record in the Eastern Conference. It is unclear what the argument stemmed from. It wasn't the only disagreement among Knicks teammates on Sunday. MSG cameras showed Iman Shumpert yelling at Carmelo Anthony during a break in the game against the Pelicans.
