PORT ST. LUCIE, Fla. — Lucas Duda will miss more time than the Mets originally assumed. He will not swing for the next week.

Manager Terry Collins said Duda would originally be able to swing by Friday.

Duda irritated his intercostal muscle while swinging. He has not swung for the past few weeks.

"We got a long time to get you ready and we can certainly get that done," Collins relayed to Duda. "But you've got to be patient and get rid of this thing so it doesn't flare up again."

Duda enters spring training with a starting position definitely his own for the first time after hitting 30 home runs last season, third most in the National League.
