"I'm very confident this is not the type of injury that will have long-lasting effects," Luhnow said. "The biggest effect it will have is that he will miss some time in the short term. Being 19 years old and the special talents that he has, I don't expect this to be much more than a blip on the radar and just a timing thing more than anything else."
Luhnow said he expects to be able to provide more detailed information about the injury on Wednesday.
"I know the nature of the injury," Luhnow said. "I don't want to talk the specifics right now. I will be in a position to talk about it tomorrow."
While Luhnow said again that he expects Correa to miss significant time, he said he doesn't know if that means he'll miss the rest of the Minor League season.
Correa was carried off the field Saturday after hurting the ankle following an RBI triple in the sixth inning. Luhnow said the injury was a result of an unfortunate incident where Correa was playing hard.
The 19-year-old Correa was hitting .325 with six home runs and 57 RBIs in 62 games this season at Lancaster. He was expected to be promoted to Double-A Corpus Christi soon, with an on-base percentage of .416 and an OPS of .926. Luhnow did not rule out the possibility that Correa could still play for Double-A this season.
"It was likely that he was going to spend a significant portion of the second half in Corpus," Luhnow said. "I consider what he did in High A this year as having checked the box of dominating that level. I do think he would have and still may spend time in Corpus Christi."
On Tuesday it was announced that Correa was selected to play in the 2014 All-Star Futures Game. It's unlikely Correa will be available for the game, which will be played on July 13 at Target Field in Minneapolis. Correa played in the game last year after he was voted onto the roster in the first-ever Futures Finalists Vote.
