Doolittle is dealing with some inflammation in his right knee, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Doolittle was placed on the 10-day injured list Thursday, and manager Dave Martinez later revealed that the lefty is experiencing some inflammation. It's unclear how long Doolittle will be sidelined as a result. He's displayed decreased fastball velocity over his first several appearances, and the injury could have played a role in the downturn in production.
