Bad news for Knicks fans. In a last-ditch effort to recruit Trevor Ariza, LeBron James last week told Ariza he would remain with the Cavaliers past 2010, ESPN.com reported last night.

“Trevor asked LeBron if he would be in Cleveland after next season,” a source said. “And LeBron said, ‘I’ll be there. Of course, I’ll be there.’ ”

TUESDAY’S UPDATE

Unfortunately for the Cavs, Ariza, formerly of the Lakers, accepted a five-year, $33.5 million offer from the Rockets last week. That deal cannot become official until tomorrow.
