Mets manager Terry Collins said Lucas Duda (head) might be done for the season. Duda is still having headaches after crashing into the right field wall during Wednesday's game and is sitting out again Saturday while awaiting the results of an MRI. A concussion has not yet been ruled out. If his season is indeed over, he'll finish the year with a .292/.370/.482 batting line to go along with 10 homers and 52 RBI.
