The trade sending Zach Randolph and Mardy Collins to the Clippers for Cuttino Mobley and Tim Thomas is now final.

There was a last-minute concern about the physical health of Cuttino Mobley that jeopardized completion of the deal.

But the Knicks have now signed off on the trade and Mobley and Thomas will be in uniform on Tuesday when the Knicks host LeBron James and the Cavaliers at Madison Square Garden.

The trade gives the Clippers the inside scoring threat the team has sought since losing Elton Brand in free-agency.

The deal gives the Knicks sizable salary cap room, perhaps enough for two maximum contract slots, for the summer of 2010 when several NBA stars will be available on the free-agent market.
