Aroldis Chapman had a plasma-rich platelet injection in his knee Friday and the New York Yankees will re-evaluate him in two weeks.

Chapman has been bothered by a knee injury for much of the season.

Aaron Boone said it's possible that Chapman will resume playing catch and slowly returning to baseball activities next week.

"We're optimistic he'll return in an impactful way this season at some point," Boone said. "Hopefully this little timeout is something that can help freshen him up and get him back rolling for us before the end of the season."
