New York Mets outfielder Yoenis Cespedes underwent a minor procedure on Monday intended to reduce the chronic swelling in his ailing right leg.
Manager Terry Collins told reporters Cespedes had "a lot" of fluid drained from an area above his knee.
"There are bruises you get where there's a buildup of fluid," Collins said, via MLB.
"That can be very painful in that part of the leg, near the joint. That's why he was doing all the limping. So with that fluid coming out of there ... after tonight it will be up to how he feels. But if you would have seen the swelling, you would understand why he had no chance at playing."
Cespedes originally hurt his leg on April 13 when he leapt into the Citi Field stands in pursuit of a foul ball against the Miami Marlins.
The 30-year-old collided with a seat and a spectator, giving him multiple bruises.
Cespedes initially did not miss any time, but the swelling and pain had gotten worse with time, forcing him out of the line-up for the third straight game on Monday.
The Mets hope the procedure will give Cespedes the opportunity to play within the coming days.
"At the moment, we're looking at it on a day-by-day basis," Mets general manager Sandy Alderson said.
"Fortunately, we have the depth that we anticipated we would need, and so we've been able to survive his absence over the last several days. And I'm sure we'll do our best to survive over the next two or three."
