Jeremy Lin (knee) is questionable for Wednesday's Game 5 against the Heat. Lin, who hasn't played since March 24, is expected to try to practice on Monday and Tuesday. If that goes well, he has a chance to suit up Wednesday. The Knicks desperately need Lin back as Baron Davis dislocated his kneecap in Game 4. The only other point guards on the roster are Toney Douglas and Mike Bibby.
