Jared Jeffries, the Knicks key free agent acquistion, will make his debut on Monday against Boston at the Garden, nearly two months after having left wrist surgery.

"I'm getting anxious," said Jeffries, who signed a five-year, $30 million contract over the summer.

Isiah Thomas said yesterday that the forward will be used as a backup for the time being.

Stephon Marbury, who sat the final 19 minutes of Saturday's win over Milwaukee after suffering a bruised left forearm, is expected to play.
