Sandy: No update on a timetable for Harvey

NEW YORK -- While Matt Harvey tweeted Tuesday that he'll be back April 1 of next season, Mets general manager Sandy Alderson said there is no update on a timetable for Harvey's return.

"If that's his tweet, that's his tweet," Alderson said.

An MRI revealed Monday that Harvey has a partial tear in the ulnar collateral ligament in his right elbow. It'll almost certainly keep the hard-throwing phenom out for the rest of this season. If he and the team decide he should undergo Tommy John surgery, Harvey could miss the 2014 season also. Harvey was officially placed on the disabled list Tuesday.

Thank you everyone for the kind words and support. I may be done this year, but I will be back next year for April 1.

That's why Harvey's tweet Tuesday was so surprising. But Alderson said the team hasn't learned any new information regarding Harvey's injury.
