Micheal Ray Richardson, a former NBA All-Star guard, said today he has decided to stay with his Italian team rather than accept an offer from the Philadelphia 76ers.

"I'm going to stay," Richardson said following talks with Paolo Gualandi, president of Knorr Bologna. "Everything is OK now. I'm happy and they're happy."Richardson, whose two-year contract in Italy pays him $550,000 a year, had threatened to jump to the 76ers unless Knorr matched the NBA club's offer. He said Philadelphia offered him a guaranteed two-year deal for $800,000 a season.
