"We'll monitor it day to day," Miami general manager Michael Hill said. "If it becomes an issue, we will deal with it at that time. At the moment, we're taking it day to day."
Not participating in the Home Run Derby and the All-Star Game is a painful thought for Stanton. For now, he is staying optimistic.
"Find a way to beat it or cope with it," Stanton said.
Stanton had the MRI on his knee on Tuesday, and the results came back later on Wednesday afternoon. The 22-year-old has missed two straight starts, and he won't be in the lineup on Thursday in the series finale at Milwaukee.
At some point, perhaps after the season, a surgical procedure is likely for Stanton.
Asked if he was encouraged by the results of the MRI, Stanton said: "Encouraged, not encouraged, it really doesn't matter either way. Right now, we just know what's going on. It's a matter of how is it going to react and go from there."
Stanton is striving to see if he can play on Friday at St. Louis. If he can play this weekend, chances are he will participate in Monday's Home Run Derby and Tuesday's All-Star Game.
"That's what we're going to do, and hope for, and go from there," he said. "One day at a time. It's pretty important right now to kind of evaluate everything and make sure all is good to go."
Soreness to the same knee caused Stanton to miss substantial time in Spring Training.
"I think we've been lucky because he's played this long without any problems," manager Ozzie Guillen said. "I thought he was going to be a little bit worse. When we left Spring Training, we didn't know exactly what we were going to get. That's the reason we have to wait and see how he feels the next couple of days."
Stanton felt his right knee lock up in the eighth inning on Monday night in a 6-5 loss to the Brewers. In the field, he was limbering up, anticipating if he had to make a play in right field. At that point, he experienced discomfort.
"It locked up on me, and that was it," Stanton said. "I didn't have to hit after that. It's something I didn't really want to mess with right now.
Stanton is emerging as a force in the big leagues, batting .283 with 19 home runs and 50 RBIs in 78 games.
Stanton is the lone Marlin selected to the All-Star Game. His first invitation came in his third big league season, and he clearly wants to take part in the festivities in Kansas City.
As a player, Guillen was in three All-Star Games, and he missed his first one due to injury. So he understands Stanton's desire to be in Kansas City.
"Especially, your first year as an All-Star," Guillen said. "My first year I was an All-Star, I was hurt and couldn't play. I went anyway. You can't take someone's dream away from them. That's why I stay away from making the call of who is going and who is not. I can put myself in that situation, because that happened to me."
Guillen also notes that the knee ailment won't be healed in a few days.
"I think one knee problem is not going to be resolved in one or two days," he said. "The question is, can he tolerate pain to play? Or do we have to shut him down?"
