"This doesn't sound good.

Mets left fielder and rising star Daniel Murphy was flown back to New York from the Arizona Fall League last night for an MRI exam this morning on his ailing right knee.

Murphy felt discomfort in the knee during pregame batting practice Nov. 11 and hasn't played in the AFL since.

Murphy, by far the biggest (and most pleasant) surprise for the Mets this past season, already has missed time in Arizona this fall due to a lacerated forearm suffered during the league's "Rising Stars" game last month.

Murphy, who is slated to platoon in left with Fernando Tatis next season, has been tearing up the AFL when healthy. Murphy is hitting .397 with two homers and 18 RBIs in 15 games. "
